RNAseq read counts generated by FeatureCounts

Hello I used FeatureCounts to do the read counts for my RNAseq data . Do the read counts FeatureCounts provide an average or absolute total of all the reads of the exons per gene ? Is there any way to get the read count for a specific exon in a gene?

rna-seq featurecounts

They are actual read counts. You can remove the -g option which summarizes counts at gene level to get exon level counts.

genomax are the read counts a cumulative total or average of the read counts of the exons per gene

ok thanks for the answer , I now understand

ok thank you for your replies genomax and kevin

The read counts are not the average number per exon, they are close to the cumulative total, but not exactly because if a read spans a splice junction it would be counted as a read for two exons, but only contributes one count to the total gene count.
