for all the genes of mouse, how many of them have 2 intron? and then take the name of those genes
the same for 2,3,4,5,n... and take the name of those genes..
i was thinking to make a script from the annotation file but i was wondering if there is already a platform, tool, r package etc.. that is doing this.
Doesn't really get the number of introns - it gets exons - but maybe it'll help.
If you use it, you should implement each step separately to see if anything weird happens.
It should be pointed out that this is using introns per transcript, not introns per gene, which is rather poorly defined.
