How do I convert or save my data files into fastq/fastqsanger or other fasta formats?  I'm trying to run the files through Trimmomatic and the FastQC following the RNA-Seq HiSat2 pipeline but the tool doesn't accept the format my files are in fastq.gzReadsPerGene.out.tab.gz. I've gone back to GEO where I got the data from and I don't see any option for downloading the data in an acceptable fasta format. Any assistance would be greatly appreciated. Thank you.
