+  CeCILL FREE SOFTWARE LICENSE AGREEMENT
+
+Version 2.1 dated 2013-06-21
+
+
+    Notice
+
+This Agreement is a Free Software license agreement that is the result
+of discussions between its authors in order to ensure compliance with
+the two main principles guiding its drafting:
+
+  * firstly, compliance with the principles governing the distribution
+    of Free Software: access to source code, broad rights granted to users,
+  * secondly, the election of a governing law, French law, with which it
+    is conformant, both as regards the law of torts and intellectual
+    property law, and the protection that it offers to both authors and
+    holders of the economic rights over software.
+
+The authors of the CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre]) 
+license are: 
+
+Commissariat à l'énergie atomique et aux énergies alternatives - CEA, a
+public scientific, technical and industrial research establishment,
+having its principal place of business at 25 rue Leblanc, immeuble Le
+Ponant D, 75015 Paris, France.
+
+Centre National de la Recherche Scientifique - CNRS, a public scientific
+and technological establishment, having its principal place of business
+at 3 rue Michel-Ange, 75794 Paris cedex 16, France.
+
+Institut National de Recherche en Informatique et en Automatique -
+Inria, a public scientific and technological establishment, having its
+principal place of business at Domaine de Voluceau, Rocquencourt, BP
+105, 78153 Le Chesnay cedex, France.
+
+
+    Preamble
+
+The purpose of this Free Software license agreement is to grant users
+the right to modify and redistribute the software governed by this
+license within the framework of an open source distribution model.
+
+The exercising of this right is conditional upon certain obligations for
+users so as to preserve this status for all subsequent redistributions.
+
+In consideration of access to the source code and the rights to copy,
+modify and redistribute granted by the license, users are provided only
+with a limited warranty and the software's author, the holder of the
+economic rights, and the successive licensors only have limited liability.
+
+In this respect, the risks associated with loading, using, modifying
+and/or developing or reproducing the software by the user are brought to
+the user's attention, given its Free Software status, which may make it
+complicated to use, with the result that its use is reserved for
+developers and experienced professionals having in-depth computer
+knowledge. Users are therefore encouraged to load and test the
+suitability of the software as regards their requirements in conditions
+enabling the security of their systems and/or data to be ensured and,
+more generally, to use and operate it in the same conditions of
+security. This Agreement may be freely reproduced and published,
+provided it is not altered, and that no provisions are either added or
+removed herefrom.
+
+This Agreement may apply to any or all software for which the holder of
+the economic rights decides to submit the use thereof to its provisions.
+
+Frequently asked questions can be found on the official website of the
+CeCILL licenses family (http://www.cecill.info/index.en.html) for any 
+necessary clarification.

+
+The Holder undertakes that the Initial Software will remain ruled at
+least by this Agreement, for the duration set forth in Article 4.2 <#term>.
+
+
+      6.2 OVER THE CONTRIBUTIONS
+
+The Licensee who develops a Contribution is the owner of the
+intellectual property rights over this Contribution as defined by
+applicable law.
+
+
+      6.3 OVER THE EXTERNAL MODULES
+
+The Licensee who develops an External Module is the owner of the
+intellectual property rights over this External Module as defined by
+applicable law and is free to choose the type of agreement that shall
+govern its distribution.
+
+
+      6.4 JOINT PROVISIONS
+
+The Licensee expressly undertakes:
+
+ 1. not to remove, or modify, in any manner, the intellectual property
+    notices attached to the Software;
+
+ 2. to reproduce said notices, in an identical manner, in the copies of
+    the Software modified or not.
+
+The Licensee undertakes not to directly or indirectly infringe the
+intellectual property rights on the Software of the Holder and/or
+Contributors, and to take, where applicable, vis-à-vis its staff, any
+and all measures required to ensure respect of said intellectual
+property rights of the Holder and/or Contributors.
+
+
+    Article 7 - RELATED SERVICES
+
+7.1 Under no circumstances shall the Agreement oblige the Licensor to
+provide technical assistance or maintenance services for the Software.
+
+However, the Licensor is entitled to offer this type of services. The
+terms and conditions of such technical assistance, and/or such
+maintenance, shall be set forth in a separate instrument. Only the
+Licensor offering said maintenance and/or technical assistance services
+shall incur liability therefor.
+
+7.2 Similarly, any Licensor is entitled to offer to its licensees, under
+its sole responsibility, a warranty, that shall only be binding upon
+itself, for the redistribution of the Software and/or the Modified
+Software, under terms and conditions that it is free to decide. Said
+warranty, and the financial terms and conditions of its application,
+shall be subject of a separate instrument executed between the Licensor
+and the Licensee.
+
+
+    Article 8 - LIABILITY
+
+8.1 Subject to the provisions of Article 8.2, the Licensee shall be
+entitled to claim compensation for any direct loss it may have suffered
+from the Software as a result of a fault on the part of the relevant
+Licensor, subject to providing evidence thereof.
+
+8.2 The Licensor's liability is limited to the commitments made under
+this Agreement and shall not be incurred as a result of in particular:
+(i) loss due the Licensee's total or partial failure to fulfill its
+obligations, (ii) direct or consequential loss that is suffered by the
+Licensee due to the use or performance of the Software, and (iii) more
+generally, any consequential loss. In particular the Parties expressly
+agree that any or all pecuniary or business loss (i.e. loss of data,
+loss of profits, operating loss, loss of customers or orders,
+opportunity cost, any disturbance to business activities) or any or all
+legal proceedings instituted against the Licensee by a third party,
+shall constitute consequential loss and shall not provide entitlement to
+any or all compensation from the Licensor.
+
+
+    Article 9 - WARRANTY
+
+9.1 The Licensee acknowledges that the scientific and technical
+state-of-the-art when the Software was distributed did not enable all
+possible uses to be tested and verified, nor for the presence of
+possible defects to be detected. In this respect, the Licensee's
+attention has been drawn to the risks associated with loading, using,
+modifying and/or developing and reproducing the Software which are
+reserved for experienced users.
+
+The Licensee shall be responsible for verifying, by any or all means,
+the suitability of the product for its requirements, its good working
+order, and for ensuring that it shall not cause damage to either persons
+or properties.
+
+9.2 The Licensor hereby represents, in good faith, that it is entitled
+to grant all the rights over the Software (including in particular the
+rights set forth in Article 5 <#scope>).
+
+9.3 The Licensee acknowledges that the Software is supplied "as is" by
+the Licensor without any other express or tacit warranty, other than
+that provided for in Article 9.2 <#good-faith> and, in particular,
+without any warranty as to its commercial value, its secured, safe,
+innovative or relevant nature.
+
+Specifically, the Licensor does not warrant that the Software is free
+from any error, that it will operate without interruption, that it will
+be compatible with the Licensee's own equipment and software
+configuration, nor that it will meet the Licensee's requirements.
+
+9.4 The Licensor does not either expressly or tacitly warrant that the
+Software does not infringe any third party intellectual property right
+relating to a patent, software or any other property right. Therefore,
+the Licensor disclaims any and all liability towards the Licensee
+arising out of any or all proceedings for infringement that may be
+instituted in respect of the use, modification and redistribution of the
+Software. Nevertheless, should such proceedings be instituted against
+the Licensee, the Licensor shall provide it with technical and legal
+expertise for its defense. Such technical and legal expertise shall be
+decided on a case-by-case basis between the relevant Licensor and the
+Licensee pursuant to a memorandum of understanding. The Licensor
+disclaims any and all liability as regards the Licensee's use of the
+name of the Software. No warranty is given as regards the existence of
+prior rights over the name of the Software or as regards the existence
+of a trademark.
+
+
+    Article 10 - TERMINATION
+
+10.1 In the event of a breach by the Licensee of its obligations
+hereunder, the Licensor may automatically terminate this Agreement
+thirty (30) days after notice has been sent to the Licensee and has
+remained ineffective.
+
+10.2 A Licensee whose Agreement is terminated shall no longer be
+authorized to use, modify or distribute the Software. However, any
+licenses that it may have granted prior to termination of the Agreement
+shall remain valid subject to their having been granted in compliance
+with the terms and conditions hereof.
+
+
+    Article 11 - MISCELLANEOUS
+
+
+      11.1 EXCUSABLE EVENTS
+
+Neither Party shall be liable for any or all delay, or failure to
+perform the Agreement, that may be attributable to an event of force
+majeure, an act of God or an outside cause, such as defective
+functioning or interruptions of the electricity or telecommunications
+networks, network paralysis following a virus attack, intervention by
+government authorities, natural disasters, water damage, earthquakes,
+fire, explosions, strikes and labor unrest, war, etc.
+
+11.2 Any failure by either Party, on one or more occasions, to invoke
+one or more of the provisions hereof, shall under no circumstances be
+interpreted as being a waiver by the interested Party of its right to
+invoke said provision(s) subsequently.
+
+11.3 The Agreement cancels and replaces any or all previous agreements,
+whether written or oral, between the Parties and having the same
+purpose, and constitutes the entirety of the agreement between said
+Parties concerning said purpose. No supplement or modification to the
+terms and conditions hereof shall be effective as between the Parties
+unless it is made in writing and signed by their duly authorized
+representatives.
+
+11.4 In the event that one or more of the provisions hereof were to
+conflict with a current or future applicable act or legislative text,
+said act or legislative text shall prevail, and the Parties shall make
+the necessary amendments so as to comply with said act or legislative
+text. All other provisions shall remain effective. Similarly, invalidity
+of a provision of the Agreement, for any reason whatsoever, shall not
+cause the Agreement as a whole to be invalid.
+
+
+      11.5 LANGUAGE
+
+The Agreement is drafted in both French and English and both versions
+are deemed authentic.
+
+
+    Article 12 - NEW VERSIONS OF THE AGREEMENT
+
+12.1 Any person is authorized to duplicate and distribute copies of this
+Agreement.
+
+12.2 So as to ensure coherence, the wording of this Agreement is
+protected and may only be modified by the authors of the License, who
+reserve the right to periodically publish updates or new versions of the
+Agreement, each with a separate number. These subsequent versions may
+address new issues encountered by Free Software.
+
+12.3 Any Software distributed under a given version of the Agreement may
+only be subsequently distributed under the same version of the Agreement
+or a subsequent version, subject to the provisions of Article 5.3.4
+<#compatibility>.
+
+
+    Article 13 - GOVERNING LAW AND JURISDICTION
+
+13.1 The Agreement is governed by French law. The Parties agree to
+endeavor to seek an amicable solution to any disagreements or disputes
+that may arise during the performance of the Agreement.
+
+13.2 Failing an amicable solution within two (2) months as from their
+occurrence, and unless emergency proceedings are necessary, the
+disagreements or disputes shall be referred to the Paris Courts having
+jurisdiction, by the more diligent Party.

+Parameters
+----------
+	  
+Data matrix file
+	| variable x sample **dataMatrix** tabular separated file of the numeric data matrix, with . as decimal, and NA for missing values; the table must not contain metadata apart from row and column names; the row and column names must be identical to the rownames of the sample and variable metadata, respectively (see below)
+	|
+
+Sample metadata file
+	| sample x metadata **sampleMetadata** tabular separated file of the numeric and/or character sample metadata, with . as decimal and NA for missing values
+	|
+	
+Variable metadata file
+	| variable x metadata **variableMetadata** tabular separated file of the numeric and/or character variable metadata, with . as decimal and NA for missing values
+	|
+
+Factor
+	| Column of the sample metadata table to be used as qualitative factor (t-test, Wilcoxon test, Analysis of variance, Kruskal-Wallis test) or quantitative variable (correlation)
+	|
+
+Test
+	| Depending on the factor of interest (qualitative with 2 or more levels, or quantitative), and on the normality of the sample values (determining whether a parametric or nonparametric test is required), you can choose one of the 6 tests available:
+

+Method for multiple testing correction
+	| The 7 methods implemented in the 'p.adjust' R function are available and documented as follows:
+	| "The adjustment methods include the Bonferroni correction ("bonferroni") in which the p-values are multiplied by the number of comparisons. Less conservative corrections are also included by Holm (1979) ("holm"), Hochberg (1988) ("hochberg"), Hommel (1988) ("hommel"), Benjamini and Hochberg (1995) ("BH" or its alias "fdr"), and Benjamini and Yekutieli (2001) ("BY"), respectively. A pass-through option ("none") is also included. The set of methods are contained in the p.adjust.methods vector for the benefit of methods that need to have the method as an option and pass it on to p.adjust. The first four methods are designed to give strong control of the family-wise error rate. There seems no reason to use the unmodified Bonferroni correction because it is dominated by Holm's method, which is also valid under arbitrary assumptions. Hochberg's and Hommel's methods are valid when the hypothesis tests are independent or when they are non-negatively associated (Sarkar, 1998; Sarkar and Chang, 1997). Hommel's method is more powerful than Hochberg's, but the difference is usually small and the Hochberg p-values are faster to compute. The "BH" (aka "fdr") and "BY" method of Benjamini, Hochberg, and Yekutieli control the false discovery rate, the expected proportion of false discoveries amongst the rejected hypotheses. The false discovery rate is a less stringent condition than the family-wise error rate, so these methods are more powerful than the others."

+variableMetadata_out.tabular
+	| **variableMetadata** file identical to the file given as argument, except that (at least) three columns have been added:
+	| 1) [factor]_[test]_[class'a']-[class'b']_dif or [factor]_[test]_cor: difference of the means (ttest) or the medians (wilcoxon) between the two classes, or 'pearson' or 'spearman' correlations
+	| 2) [factor]_[test]_[class'a']-[class'b']_[method] or [factor]_[test]_[method]: adjusted p-values
+	| 3) [factor]_[test]_[class'a']-[class'b']_sig or [factor]_[test]_sig: significance (coded as '1' if below the threshold and '0' otherwise)
+	| In the case of 'anova' and 'kruskal', the columns 2) and 3) appear first to give the results from the ANOVA or Kruskal Wallis test, and, when these tests are significant, the results of the pairwise comparisons are reported in additional columns (otherwise NA in these columns): in the case of ANOVA, the Tukey HSD post-hoc analysis is used (for each comparison, the difference between means, p value, and significance are provided); in the case of Kruskal Wallis, the Nemenyi is performed (PMCMR package) (for each pairwise comparison, the difference between medians, p value and significance are provided)
