We'd like to be able to associate fixed things (project, Sample, sequencer used) with user's FASTQ files, and we'd also like to allow users to associate dynamic, site-specific stuff with the sequencing run. Currently, users track their runs using a CSV sample sheet, and often they add columns to that sample sheet for their own information. Is it possible to associate that information with the FASTQ file when it is placed in Galaxy? I know about metadata, but the supported fields look like they are fixed in the code. I was hoping for a solution where the users do not need to modify the Galaxy code to pull this off.
