Hello all, Bjoern and I were talking about doing some work on more datatype definitions, but this raises the question about how to handle dependencies. First of all, complex datatypes in Galaxy are defined using Python code, so any Python dependency must be available to the main Galaxy process (unlike Python dependencies for jobs which are run on separate processes). For example, if I wrote GenBank/EMBL definitions using Biopython, could this dependency be handled via the Tool Shed? Second, the Python code for some datatypes may call a binary command line tool. For example, I was thinking of using the blastdbcmd binary within the BLAST database file format definitions to provide more useful peek information. Again, how could this dependency be handled via the Tool Shed? Thanks, Peter
