Hi: My name is Ying, a postdotoral associate working in Yale university. I am trying to use tophat in galaxy to analyze paired-end RNA-seq data, however, after I groomer and use tophat to analyze them, I only got an empty file. I am wondering what is the problem here. One thing I am concerned is that my files is kind of large, e.g., for each end I got a file with 20.7 gb, so totally 41.4 gb for both ends of this sample. So do you think it is because the files are too big? Also when the genome center sent me the data, they already separate the two ends into two files, so I uploaded two files for one sample, but when do tophat analysis, do I need to merge those two files into one file? do you know what is the usual parameter set up for paried-end RNA-seq analysis(with a 300 bp fragment)? Thank you very much! I really appreciate your help!
