Hi all,
I am running a single fastq file for HUMAnN in cluster with the following code:
conda activate humann
humann -i file.fq -o file_humann --threads 40
I am running this command on a cluster with 24CPUs and 50Gb memory with 40 threads.
I am getting the ERROR: Unexpected end of input files.
Could anyone please guide me in this? The error screenshot is pasted below-
I tried running demo fastq file provided with HUMAnN, yet I am getting the similar error, might be something to do with my HUMAnN installation. Any leads? Error is thrown from Diamond
Hmm, my first guess was the number of threads - we have seen errors in alignment with very large numbers of threads getting out of step with file I/O, leading to errors like this. In your demo run though it looks like you’re only using one thread though.
My next guess is an incompatibility with the newest version of DIAMOND (2.0.15). HUMAnN 3.0 was notably built/tested against DIAMOND 0.9.36, the end of the pre-2.0 lineage. I have seen it used successfully on DIAMOND 2.0+ but it’s possible something has changed recently that resulted in this error. I would try rolling back to an earlier DIAMOND and see if that fixes the problem.
