200 Overview
|
|
|
201 --------
|
|
|
202 FeatureCounts is a light-weight read counting program written entirely in the C programming language. It can be used to count both gDNA-seq and RNA-seq reads for genomic features in in SAM/BAM files.
|
|
|
203 It has a variety of advanced parameters but its major strength is its outstanding performance: analysis of a 10GB SE BAM file takes about 7 minutes on a single average CPU (Homo Sapiens genome) [1].

205 Input formats
|
|
|
206 -------------
|
|
0
|
207 Alignments should be provided in either:
|
|
5
|
208
|
|
|
209 - SAM format, http://samtools.sourceforge.net/samtools.shtml#5
|
|
|
210 - BAM format
|
|
0
|
211
|
|
|
212 Gene regions should be provided in the GFF/GTF format:

218 ------------

|
220 1. Make sure you have proper GFF/GTF files (corresponding to your reference genome used for the aligment) uploaded to your history.
|
|
0
|
221
|
|
5
|
222 2. Make sure that your gene_sets.loc is configured properly as data table. This is generally done by copying the right information into: tool_data_table_conf.xml. More info at: https://wiki.galaxyproject.org/Admin/Tools/Data%20Tables
