I am following a tutorial from openms which involves a workflow using OMSSA in KNIME. Upon inputting my own work files and Uniprot database, I get the following error. It seems that KNIME is unable to find the executable file. I suspected it might be caused by the space in the KNIME application name (originally /Applications/KNIME 4.1.0.app/…). However, after changing to “/Applications/KNIME-4.1.0.app/…”, the problem still persists.
ERROR OMSSAAdapter 0:9 Failing process stdout: [Warning: unable to determine the version of OMSSA - the process returned an error. Call string was: ‘/Applications/KNIME-4.1.0.app/Contents/Eclipse/plugins/de.openms.macosx.x86_64_22.214.171.124004161737/payload/bin/OMSSA/omssacl -version’. Make sure that the OMSSA executable given in ‘-omssa_executable’ is correct!, OMSSAAdapter took 0.01 s (wall), 0.01 s (CPU), 0.00 s (system), 0.01 s (user).]

Anyone encounter the same issue and knows the solution?
