I ended up with this error message after using Maker in the Main Galaxy instance: “Possible unintended interpolation of @2 in string …”. My attempts to autodetect the metadata to correct the problem did not work.
I saw that others had this error with other tools (e.g. Trinity) within the last couple years. In one case, @jennaj said the error meant insufficient memory was allotted to the job or that the inputs were wrong. Hoping this was the case, I checked the input and ran the job again, but got the same result.
In another case, Matthias Bernt said it was a miscommunication between Galaxy, which uses the “@” symbol, and the perl interpreter that doesn’t know what to do with it. He suggested adding a " \ " in front of the “@”, although I don’t know how to access the script to do this.
Any other ideas on how to handle this type of error? I still can’t tell whether it’s possible to salvage my results, which were apparently successfully run aside from the metadata problem that couldn’t be resolved. Or should I simply keep rerunning the job until it works?
I got this error while doing the genome annotation tutorial, but I want to know how to avoid this issue when I’m using my data.
