Please note that there are tools available to convert FastQ to FastA in the event that FastQ is incompatible with the tool you’re using:.

MapSplice performs well for both reads alignments and splicing junction calling according to two assessment papers 17 , 18. Because TopHat2 needs gene annotation file for better alignment, you could select one GTF file from hg19_ref.gtf, hg19_kg.gtf and hg19_ens.gtf. This has been a relevant concern over the years as evidenced by here, here, here, here, here, here, here, and etc., and continues to be as Tophat usage persists (for example, Wang et al.

Your results are normal, the MAPQ scores reported by tophat2 are not related to -10*log10 (probability the mapping is wrong). I think it’s a shorter list to tell you what does not work with FastQ files. In the final stage, the independently aligned reads are analyzed together to produce paired.
