I downloaded some public SOLiD data files in sra and fastq format. All files, i guess, are from cfasta+qual merged together. I want to count k-mers with jellyfish software and don't know if i need to somehow convert solid sra\fastq in fastq\fasta with nucleotides. For mapping there are suggestions not to convert because of potential numerous mistakes in reads. I thought, there is one simple way: convert data in cfasta+qual and than convert cfasta in ordinary fasta. Am I right? Fortunately, there are many scripts for conversion.
