How To Either Converting Fastq To Srf Or Subselecting Reads From A Srf File?

Question

[Pablo Marin-Garcia]

I am writing tests for my pipeline modules and I would like to test my srf2fastq steps. Therefore I would like to create a small srf file either sub-selecting from an existing SRF file or creating the SRF file from a FASTQ with a few reads. I would prefer to do the later so I would select a bunch of reads in a region (bam->fastq->srf) and I will use the same fastq file for the align test etc..
