Could you try with something shorter for -p? The entire directory path as a prefix is likely to trip things up. Perhaps just -p test

Tried, same error

runCA -d test/ -p datafastq/ datafastq/lg/human/humanUpaired.frq

I have no idea if this causes the problem, but again you used a directory rather than a prefix for -p. Try (as in the manual) to just use a string and not a path or directory.

I am not sure if you are aware, but... "If you are assembling PacBio or Oxford Nanopore data, please use Canu instead. Celera Assembler is no longer being maintained." see:

I remember having many issues with CA in the past, but Canu has been working great. It may be worth upgrading.
