.. class:: infomark
  
This tool extracts spectra from ion-wise aligned MS(/MS) results. It uses expression profiles and 
retention times of the putative ions to cluster them. Each cluster is then used to generate 
one spectrum containing the clustered ions (peaks).

-----

**Input**

The input file should contain the following columns (in this order), followed by the sample intensity columns (one column with the
intensity value for each sample):

*ScanNR*
	
*Ret(umin)*
	
*Mass(uD)*
	
*(Optional)retentionMean*

*(only required if retentionMean is present)retentionSD*

*N sample intensity columns...*


-----

**Output**

This tools returns a number of ouptut files and a small report. 

**Parameters index**


*Select the approach used for imputing missing values:* only select this if you have used a specific method to 
fill in the data gaps in the input file. One example is replacing zero values by some randomly generated low value.
If MeTot is chosen, then a value is considered generated if: the value contains a dot '.' and some number 
other than 0 (zero) after the dot. 

*Effective Peaks:* Neighborhood window size to consider when calculating density. Smaller values increase 
performance but are less reliable.

*Peak Width, in scans:* Scan window width of scans to consider 'close'. One can see this as the 
'tolerated variation in scans' for the apex positions of the fragment peaks composing a cluster. 
Note: if MetAlign was used, this is the variation *after* pre-processing by MetAlign.   

*Peak Width confidence:* The higher the confidence, the stricter the threshold.

*Correlation threshold (0.0 - 1.0):* Tolerance center for pearson distance calculation. The higher this value, 
the higher the correlation between 2 items has to be for them to be considered 'close'. 

*Correlation threshold confidence:* The higher the confidence, the stricter the threshold. `More...`__

*Potential Density reduction (0.0 - 1.0):* Reduction tolerance center for pearson distance calculation. 
The higher this value, the less the low correlated items get reduced, getting a chance to form a cluster of their own. 

*Potential Density reduction softness:* Reduction curve slope for pearson distance tolerance. Lower 
values = stricter separation at the value determined in 'Potential Density reduction' above  
(TODO review this comment). 

*Stop Criterion:* When to stop reducing and looking for new clusters. Lower values = more iterations

**Output files described below**

-----

*SPECTRA:* this file can be submitted to NIST for identification of the spectra.

-----

*MIC:* stands for Measured Ions Count -> it contains, for each cluster, the sum of the ion count 
values (corrected by their membership) for all MEASURED cluster ions in the given sample.

The MIC for a **cluster i** in **sample s**, where **cluster i** has **n** members is thus: 

sum ( [intensity of member n in **sample s**] x [membership value of member n in **cluster i** ] )

-----

*SIM:* stands for Selective Ion Mode ->  it contains, for each cluster, the intensity values of the 
most representative member ion peak of this cluster. The most representative member peak is the one with the 
highest membership*average_intensity. This definition leads to conflicts as a peak can have a 
membership in two or more clusters. The assignment of a SIM peak to a cluster depends on 
the configured data type (LC or GC-MS). NB: this can be overruled in the "advanced settings":

(1) LC-MS SIM: select SIM peak only once and for the centrotype in which this specific mass has its 
highest membership; for neighboring centrotypes use its "second best SIM", etcetera. In other words,
if the SIM peak has been identified as the SIM in more than 1 cluster, assign as SIM to the cluster 
with highest membership. Continue searching for other SIM peaks to assign to the other clusters until 
all ambiguities are solved.

(2) GC-MS SIM: the SIM peak can be "shared" by multiple clusters. However, the intensity values are corrected
by the membership value of the peak in the cluster in case the SIM peak is "shared". If the SIM peak is not 
"shared" then the "raw" intensity values of the SIM peak are recorded in the SIM file.
