Hello, When we try to add a column to a dataset we get the following error: An error occurred running this job: *Args must match #! line at /share/shared/galaxy-central-hbc/tools/filters/fixedValueColumn.pl line 1. * Perl documentation says this; (F) The setuid emulator requires that the arguments Perl was invoked with match the arguments specified on the #! line. Since some systems impose a one-argument limit on the #! line, try combining switches; for example, turn "-w -U" into "-wU". It works on our development instance without error. -Robert Chase
