Hi, In the past I installed bwa_wrapper from the toolshed. Unfortunately I must have choosen a wrong category. Currently it is not part of any tool section. According to integrated_tool_panel.xml it's supposed to be part of this section: <section id="ngs:_assembly" name="NGS: Assembly" version=""> while it contains another section with the same name and a different id: <section id="ngs_assembly" name="NGS: Assembly" version=""> I tried to rectify this by deleting and reinstalling but unfortunately there is no way to really reinstall and it always ends up with the same problem again. Is there a way to really uninstall? regards, Andreas -- Andreas Kuntzagk SystemAdministrator Berlin Institute for Medical Systems Biology at the Max-Delbrueck-Center for Molecular Medicine Robert-Roessle-Str. 10, 13125 Berlin, Germany http://www.mdc-berlin.de/en/bimsb/BIMSB_groups/Dieterich
