Hi all, So I am using this documentation<http://wiki.galaxyproject.org/Admin/Tools/Multiple%20Output%20Files#Number_of_Output_datasets_cannot_be_determined_until_tool_run>to create a tool that has a variable number of output files based upon the input file. I have gotten it to work, however, the intermediate files which I create in the $__new_file_path__ directory (which are then copied into the database as history files) are not being deleted upon tool completion. Is there a way to get galaxy to automatically delete these files, or is there some programmatic way to do it? - Nik. -- Nikhil Joshi Bioinformatics Analyst/Programmer UC Davis Bioinformatics Core http://bioinformatics.ucdavis.edu/ najoshi -at- ucdavis -dot- edu 530.752.2698 (w)
