RepeatScout errors

[fripeki]

Hello everybody
I was trying to use RepeatScout. I was following some steps one by one to analyze my sequences.
Here there are the passages:

Repeatscout run: using `fname.fa`

1) `./build_lmer_table -l 15 -sequence fname.fa -freq fname.freq`

2) `./RepeatScout -sequence fname.fa -output fnamescout.fa -freq fname.freq -l 14`

Then the next step would be:

3) `cat fnamescout.fa | ./filter-stage-1.prl> fnamescout_filtered.fa`

but it generated an empty output file .fasta



I checked if `TRF` was installed, then I installed `NSEG`. It could be okay.
What's wrong?
