Hello,

Is it possible to let a tool in a workflow manage the users history? For instance, I have a tool that takes a variable number of user-uploaded CSV files as input and merges them into one file. Before running this tool, the user thus has a number of CSV files in the history which I would like to 'replace' with the single merged file.
I was hoping that when I remove a file from disk that it would also be removed from the history, but that only results in a 'The resource could not be found.' error.
Alternatively, is it possible to create a composite datafile/history item from uploaded files? In any case, I would like to remove the separately uploaded files from the users history which makes selecting files for the next step(s) easier.

(this is a bit of a followup for: http://gmod.827538.n3.nabble.com/Creating-new-datatype-with-variable-number-of-input-files-td2248444.html)

One other question, is there (any) documentation available on the Galaxy API or a set of example files?

Thanks for your input!

Regards,

Marcel.
