Question

[Chvatil]

Hello I'm writting because I'm facing when I run RepeatModeler.

Here is the code I used :

Sp_name=Tryphoninae_B
ASSEMBLY=/beegfs/data/these/Genomes/Tryphoninae_B/Tryphoninae_B.fa

cd /beegfs/data/these/Genomes/Tryphoninae_B/run_reapeat/
/beegfs/data/TOOLS/RepeatModeler/BuildDatabase -name $Sp_name.DB -engine rmblast $ASSEMBLY
echo 'BuildDatabase done' 
echo date 

/beegfs/data/TOOLS/RepeatModeler/RepeatModeler -database $Sp_name.DB -pa 6 -LTRStruct
echo 'RepeatModeler done '

Here is the error message I got :

  WARN: The N50 for this assembly is low ( <10,000 ).  The de novo methods
        employed by RepeatModeler are intended for use with long contiguous
        sequences and may not perform well with an over-abundance of short
        contigs in the database.

Ready to start the sampling process.
INFO: The runtime of RepeatModeler heavily depends on the quality of the assembly
      and the repetitive content of the sequences.  It is not imperative
      that RepeatModeler completes all rounds in order to obtain useful
      results.  At the completion of each round, the files ( consensi.fa, and
      families.stk ) found in:
      /beegfs/data/these/Genomes/Tryphoninae_B/run_reapeat/RM_750.MonNov231452352020/ 
      will contain all results produced thus far. These files may be 
      manually copied and run through RepeatClassifier should the program
      be terminated early.

Do you have an idea of what is going on please ?
