  • problem with signalP not working

    Hello everybody, and thank you to have accepted me in the forum!

    I am trying to make signalP 4.1 working on iOS 10.13.3 since days and I hope that someone can help me

    I downloaded the package for the darwin system and followed the installation instructions. But when I made the test

    > ./signalp -t euk -f short test/euk10.fsa > euk10.fsa.short_out

    I obtained a different output then expected

    ----
    # SignalP-4.1 euk predictions
    # Measure Position Value Cutoff signal peptide?
    max. C 1 0.000
    max. Y 1 0.000
    max. S 1 0.000
    mean S 1-0 0.000
    D 1-0 0.000 0.450 NO
    Name= SP='NO' D=0.000 D-cutoff=0.450 Networks=SignalP-noTM

    and the same if I test a home made file of amminoacid contigs like this

    with this command

    ./signalp -t euk -f short /path/prova2.fasta > /path/output.txt

    I get this output file

    ----
    # SignalP-4.1 euk predictions

    but no error message appeared... someone know what can be the problem?

    Thank you for any help!

    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
