Platanus-allee phasing fail: Error(13): Error, SolveDBG exception!!

Question

[Sadik Muzemil]

Hello there,

I am using Platanus-allee 2.2.2 to generate hybrid assembly of Illumina short reads and PacBio reads. I have got contigs.fa from short reads but phasing step with PacBio reads gives the following error after running for couple of hours

Error(13): Error, SolveDBG exception!! platanus_allee solve_DBG command failed.

Here is the script used for contig assembly and phasing

num_threads=20 
tmp_dir=/path-to-/tem/platanus_allee 
memory_GB=100 
out_prefix=out
minimap2_path=minimap2

# Input reads

PE=trimmed_L1_*.fq
PacBio=pacbio*.fastq.gz

# Contig assembly commands
platanus_allee assemble -t ${num_threads} -tmp ${tmp_dir} -m ${memory_GB} -o ${out_prefix} \
-f $PE \
2>${out_prefix}.assembleLog

# phasing commands 
platanus_allee phase -t ${num_threads} -tmp ${tmp_dir} -o ${out_prefix} -mapper ${minimap2_path} \
-c out_contig.fa \
-IP1 $PE -p $PacBio \ 
2>${out_prefix}.phaseLog

cat out.phaseLog

platanus_allee version: 2.2.2
platanus_allee phase -t 20 -tmp /path-to-/tem/platanus_allee -o out -mapper minimap2 -c out_contig.fa -IP1 trimmed_L1_1.fq trimmed_L1_2.fq -p /path-to-/pacbio*.fastq.gz

A bug causing the segmentation fault seems issue on Platanus-allee v2.0.0 and earlier

Any suggestion please?

I'm running into the same issue - platanus_allee assemble worked, but I get the error code when running the phasing command.

Did you end up finding a solution?

Hi, I did not find a way to work it out and finally gave up on it and switched to my focus to SPAdes.

Hello, I am also getting the same error using the 2.2.2 version. Also wrote to the authors but no answer. Did anybody found a solution? The original paper has been cited 25 times (according to WOS) so I assume this error is not a bug?
