DESCRIPTION

       trimest is a command line program from EMBOSS (“the European Molecular Biology Open
       Software Suite”). It is part of the "Nucleic:Functional sites,Edit" command group(s).

OPTIONS

   Input section
       -sequence seqall

   Additional section
       -minlength integer
           This is the minimum length that a poly-A (or poly-T) tail must have before it is
           removed. If there are mismatches in the tail than there must be at least this length
           of poly-A tail before the mismatch for the mismatch to be considered part of the tail.
           Default value: 4

       -mismatches integer
           If there are this number or fewer contiguous non-A bases in a poly-A tail then, if
           there are '-minlength' 'A' bases before them, they will be considered part of the tail
           and removed . For example the terminal 4 A's of GCAGAAAA would be removed with the
           default values of -minlength=4 and -mismatches=1 (There are not at least 4 A's before
           the last 'G' and so only the A's after it are considered to be part of the tail). The
           terminal 9 bases of GCAAAAGAAAA would be removed; There are at least -minlength A's
           preceding the last 'G', so it is part of the tail. Default value: 1

       -reverse boolean
           When a poly-T region at the 5' end of the sequence is found and removed, it is likely
           that the sequence is in the reverse sense. This option will change the sequence to the
           forward sense when it is written out. If this option is not set, then the sense will
           not be changed. Default value: Y

       -tolower toggle
           The poly-A region can be 'masked' by converting the sequence characters to lower-case.
           Some non-EMBOSS programs e.g. fasta can interpret this as a masked region. The
           sequence is unchanged apart from the case change. You might like to ensure that the
           whole sequence is in upper-case before masking the specified regions to lower-case by
           using the '-supper' sequence qualifier. Default value: N

   Advanced section
       -fiveprime boolean
           If this is set true, then the 5' end of the sequence is inspected for poly-T tails.
           These will be removed if they are longer than any 3' poly-A tails. If this is false,
           then the 5' end is ignored. Default value: Y

   Output section
       -outseq seqoutall
