Why does Exec RepeatMasker ProcessRepeats Fails?

Question

[eennadi]

I am trying to mask repeats using RepeatMasker. The software dies at this stage. I don't seem to have a solution for. No other error message is given.

Exec ~/exe/RepeatMasker/ProcessRepeats -lib ~/maker/mycustom_repeat.fa -orifile ~/22_09_19_flye/racon3x_pilon3x/MUCU_Flye_racon3_pilon3.fasta -maskSource ~/braker_annotation_08092020/RM_406998.WedSep91725412020/MUCU_Flye_racon3_pilon3.fasta ~/braker_annotation_08092020/RM_406998.WedSep91725412020/MUCU_Flye_racon3_pilon3.fasta.cat.gz failed

About the RepeatMasker I used

RepeatMasker version 4.1.0 Search Engine: NCBI/RMBLAST [ 2.9.0+ ]

INFO: For this species, RepeatMasker is using the new Dfam consensus sequences. These are based on the Dfam seed alignments and may differ from the ones in RepBase.

Could you share your input files, mycustom_repeat.fa, MUCU_Flye_racon3_pilon3.fasta, MUCU_Flye_racon3_pilon3.fasta.cat.gz?*

Some ideas:

• how did you install or invoke RepeatMasker, are you missing some dependencies?
• system information, OS? Is that Linux? Try to install latest version with Bioconda
• I think latest version is RepMasker v4.2 now, install the update
• really no error log, possibly the output is dumped into a log file? Try to run the failing command in a terminal, possible to se more there.
• why is there a gzip compressed file on the command line, is that intentional?
