Hi Carson,

For the final run of annotation, I would like to incorporate tophat 
results from RNA-seq data, from your experience, do you know if it is 
better to use raw RNA-seq (Illumina paired-end data) or trimmed (trimmed 
using Trimmomatuc) data for feeding into tophat? If trimmed, do you 
recommend a particular programme?

Thanks for your time.

Best Regards
KAren
