I’m currently setting up a Nextflow pipeline together with a colleague to run certain steps of QIIME2 in a nextflow automated script. For this, I created a Docker Image containing all tools required by QIIME2 (basically copying the QIIME2 environment.yaml) and then started running things. Most run well, but the classifier apparently runs out of disk space every time with some test data.
OSError: [Errno 28] No space left on device Plugin error from feature-classifier: [Errno 28] No space left on device
Trying to set TMPDIR etc via Nextflow didn’t help at all unfortunately - can someone maybe elaborate where this step stores temporary data in general?
