Error while training

I have been testing gnomic in training mode, and got the next output:

Which seems really weird to me. Indeed, the training.smap file does not contain a '\t' string, and clearly is doesn't have more than two columns.

I've had this happen before and I think I worked around it by remaking the file using awk and making sure it's " " delimited. Also, not sure if it will help, but maybe check if there is an extra '\n' at the end of the file? My smap files only have 2 columns though (sampleID and the reference the sample is assigned to).
