Hi Greg or James, This morning I got a question about the Aggregate Datapoints tool which only returned nan results. in line 204@ aggregate_scores_in_intervals.py<https://bitbucket.org/galaxy/galaxy-dist/src/95bf71620d50c6d81248eef2001a7dc156ae1088/tools/stats/aggregate_scores_in_intervals.py?at=default> I found out that the if not is NaN ( score ): should be if not isnan( score ): on https://usegalaxy.org/tool_runner?tool_id=aggregate_scores_in_intervals2 the tool also seems to be failing. I hope you could use this, Eric ---------- Forwarded message ---------- From: Sandra Gavaldá Martín Date: 26 January 2014 20:52< Subject: Galaxy tool is not running To: "Kuijt, Eric" <eric.kuijt@wur.nl> Hello Eric, My name is Sandra Gavaldá and I am very grateful for Galaxy tools. I usually use the one "Aggregate datapoints" for fusioning files with intervals and my .wig files. I noticed you made some updating and I do not why I can not obtain any result now. -- Central Veterinary Institute of Wageningen UR (CVI) Department of Infection Biology PO box 65, 8200 AB Lelystad, NL Visiting address: ASG, Edelhertweg 15, 8219 PH Lelystad Tel: +31-(0)320-293391 Fax: +31-(0)320-238153 E-mail: eric.kuijt@wur.nl Web: http://www.cvi.wur.nl
