cleanup.pl Bug?

[asgray]

Hi, I'm in the process of updating to 2.9.9 from 2.9.0 and I'm seeing some odd outputs:

~/projects/LTR_retriever$ ./LTR_retriever -genome dmel-smaller.fa -inharvest raw-struct-results.txt

                                Sequences with 10 missing bp or 0.8 missing data rate will be discarded.
                                Sequences containing tandem repeats will be discarded.

        Usage: perl cleanup.pl -f sample.fa [options] > sample.cln.fa 
        Options:
                -misschar       n       Define the letter representing unknown sequences; case insensitive; default: n
                -Nscreen        [0|1]   Enable (1) or disable (0) the -nc parameter; default: 1
                -nc             [int]   Ambuguous sequence len cutoff; discard the entire sequence if > this number; default: 0
                -nr             [0-1]   Ambuguous sequence percentage cutoff; discard the entire sequence if > this number; default: 1
                -minlen         [int]   Minimum sequence length filter after clean up; default: 100 (bp)
                -cleanN         [0|1]   Retain (0) or remove (1) the -misschar taget in output sequence; default: 0
                -trf            [0|1]   Enable (1) or disable (0) tandem repeat finder (trf); default: 1
                -trf_path       path    Path to the trf program

Mon Feb 12 03:56:34 PM PST 2024 0 clean candidates remained

cp: cannot stat 'dmel-smaller.fa.mod.retriever.scn.adj': No such file or directory
Mon Feb 12 03:56:34 PM PST 2024 No LTR-RT was found in your data.

Mon Feb 12 03:56:34 PM PST 2024 All analyses were finished!

I believe the command that calls cleanup.pl is: perl ./bin/cleanup.pl -trf 1 -trf_path /usr/local/bin/trf -misschar N -nc 10 -nr 0.8 -minlen 100 -minscore 1000 -f dmel-smaller.fa.mod.ltrTE.fa > dmel-smaller.fa.mod.ltrTE.stg1

What is the expected behavior here?

You have very few candidates to begin with, and the clean up process may determine all of them not valid.

Hi @oushujun,

Should the line $trf=0 if /^-trf$/i and $ARGV[$k+1]!~/^-/; be changed to $trf=$ARGV[$k+1] if /^-trf$/i and $ARGV[$k+1]!~/^-/; in cleanup.pl?

I noticed that when specifying perl ./bin/cleanup.pl -trf 1, the trf program is not executed.

Good catch! You are correct. I have updated the code, and it will be pushed to GitHub in the next update. I don't think it's the solution of the initial post though.
