Hi all

I'm used the following mapper script for miRNA alignment in miRdeep2. I am getting error and also the reads_vs_genome.arf is empty. I am posting the error message herewith

    mapper.pl trim_3_SRR7189567.fastq -e -j -k TCGTATGCCGTCTTCTGCTTGT -l 18 -m -p /home/shanthi/Desktop/Nivya/indexed_genome/genome.fa -s collapsed_reads.fa -t collapsed_reads_vs_genome.arf -v -n -h
    parsing fastq to fasta format
discarding sequences with non-canonical letters
clipping 3' adapters
discarding short reads
collapsing reads
mapping reads to genome index
usage: /home/shanthi/miniconda2/bin/convert_bowtie_output.pl reads_mapped.bwt
trimming unmapped nts in the 3' ends
Log file for this run is in mapper_logs and called mapper.log_28941
