+**GffCompare Overview**
+
+## GffCompare
+* compare and evaluate the accuracy of RNA-Seq transcript assemblers (Cufflinks, Stringtie).
+* collapse (merge) duplicate transcripts from multiple GTF/GFF3 files (e.g. resulted from assembly of different samples)
+* classify transcripts from one or multiple GTF/GFF3 files as they relate to reference transcripts provided in a
+annotation file (also in GTF/GFF3 format)
+
+More information can be found here: https://ccb.jhu.edu/software/stringtie/gffcompare.shtml.
+
+The original form of this program is also distributed as part of the Cufflinks suite, under the name "CuffCompare"
+(see manual: http://cole-trapnell-lab.github.io/cufflinks/cuffcompare/). Most of the options and parameters of CuffCompare
+are supported by GffCompare, while new features will likely be added to GffCompare in the future.
+
+A notable difference of GffCompare is that when a single query GTF/GFF file is given as input, along with a reference annotation (-r option),
+gffcompare switches into "annotation mode" and it generates a .annotated.gtf file instead of the .merged.gtf produced by CuffCompare with the
+same parameters. This file has the same general format as CuffCompare's .merged.gtf file (with "class codes" assigned to transcripts as per
+their relationship with the matching/overlapping reference transcript),  but the original transcript IDs are preserved, so gffcompare can thus
+be used as a simple way of annotating a set of transcripts.
+
+Another important difference is that the input transcripts are no longer discarded when they are found to be "intron redundant", i.e.
+contained within other, longer isoforms. CuffCompare had the -G option to prevent collapsing of such intron redundant isoforms into
+their longer "containers", but GffCompare has made this the default mode of operation (hence the -G option is no longer needed
+and is simply ignored when given).
