checktrans(1) Reports STOP codons and ORF statistics of a protein


checktrans -sequence seqall -orfml integer [-addlast boolean] -outfile outfile -outseq seqoutall -outfeat featout
checktrans -help



is a command line program from EMBOSS ("the European Molecular Biology Open Software Suite"). It is part of the "Nucleic:Gene finding,Nucleic:Translation" command group(s).


Input section

-sequence seqall

Required section

-orfml integer

Default value: 100

Additional section

-addlast boolean

An asterisk in the protein sequence indicates the position of a STOP codon. Checktrans assumes that all ORFs end in a STOP codon. Forcing the sequence to end with an asterisk, if there is not one there already, makes checktrans treat the end as a potential ORF. If an asterisk is added, it is not included in the reported count of STOPs. Default value: Y

Output section

-outfile outfile

-outseq seqoutall

Sequence file to hold output ORF sequences

-outfeat featout

File for output features
