Merger not working

[amir-zeldes]

I have the same documents in two formats: TreeTagger and conll. Both formats convert correctly to PAULA individually. However, using both sources and the merger module, I get the following error, which looks like the output directory cannot be created (although in fact it is created and remains empty):

Here is my pepperparams (the data can be found in the GUM repo, I'm using the 'ants' document from the folders dep/ (conll format) and xml/ (tt format, I renamed the files to .tt). The OS is Win10 64. Each of the import conversions runs fine if I comment out the other, as well as the merging module.

OK, I think the problem is not the merging module - exporting to relANNIS does work, so this is possibly a problem with the PAULA module. I'm moving this issue to the PAULA repo.
