#5 error but log is empty

[Nick Youngblut]

I'm using maxbin2 2.2.4 h470a237_1 bioconda, and running the following:

run_MaxBin.pl -min_contig_length 1500 -markerset 40  -prob_threshold 0.8 -thread 24 -contig contigs.fna  -abund_list abund_file_list.txt  -out maxbin_bins

I'm getting the following error:

MaxBin 2.2.4
Min contig length: 1500
Switch to 40 marker genes universal for bacteria and archaea.
Probability threshold: 0.8
Thread: 24
Input contig: contigs.fna
out header: maxbin_bins
Located abundance file [...]  # I'm just not showing all of this
Searching against 40 marker genes to find starting seed contigs for [contigs.fna]...
Done data collection. Running MaxBin...
Command: /ebio/abt3_projects/vadinCA11/bin/llmga/.snakemake/conda/a1559996/opt/MaxBin-2.2.4/src/MaxBin [...] # again, I'm truncating
Error encountered while running core MaxBin program. Error recorded in contigs.log.
Program Stop.

The "contigs.log" file is empty, so I have no idea what caused the error. The contig IDs in all of the abundances files and the fasta all match, so I don't think that is the problem.

I get the same error. If I run the command stated in the log Command: ..., then that runs successfully.
Given that it's been a year since this ticket was originally created, I'm guessing the developers are not going to deal with this issue.
Generally, it would be very helpful to have better error messages.

It appears that the error was due to the output directory not existing. Adding mkdir to the code (https://perldoc.perl.org/functions/mkdir) should fix the issue
