Holle everyone! I am a beginner in RNA-Sequencing. I have a simple problem about 'tophat' software: what different on result between using -G parameter and do not use? If I use this parameter and give it a gene annotation file (e.g. gencode human V10) in reads alignment, can I use another version of annotation file (e.g. gencode human V19) when count reads number? Thank you very much!

You should know that the old 'Tuxedo' pipeline of Tophat(2) and Cufflinks is no longer the "advisable" tool for RNA-seq analysis. The software is deprecated/ in low maintenance and should be replaced by HISAT2, StringTie and ballgown. See this paper: Transcript-level expression analysis of RNA-seq experiments with HISAT, StringTie and Ballgown. There are also other alternatives, including alignment with STAR and bbmap, or pseudo-alignment using salmon.

Please stop using Tophat https://t.co/Es4ohxOEyx Cole and I developed the method in *2008*. It was greatly improved in TopHat2 then HISAT & HISAT2. There is no reason to use it anymore. I have been saying this for years yet it has more citations this year than last #methodsmatter
