Splitrim returns 0 reads

Hi!
I am trying to run GOTTCHA on a CAMI dataset (toy human microbiome) and I keep receiving the following error.

[00:05:22] No read mapped to species-level signatures. Please try again with upper-level databases.

Running the same command on different samples (not from CAMI) always results in at least some split trimmed reads. What could be the problem here?

Thanks,

UPDATE:

This seems to be an issue with multiple parts. Firstly, the CAMI samples were interleaved (read1 and read2 in the same file) and GOTTCHA doesn't seem to like that. After deinterleaving samples, I could run GOTTCHA on 15 of my 20 samples. Interestingly, for 5 samples, I got the same error, splittrim returned 0 reads. Every time I received the same error message as in this issue: #5

I tried to run splittrim separately and each run resulted in the same message, except when I tried to modify the --minQ parameter. This resulted in the following error:

Just as a sanity check I checked the first few reads of my samples and they seem to be in order:

I suspect that the developers don't really care about this project anymore, still, I hope somebody will see this and can offer some help!

Thanks
