It is part of the "Nucleic:Functional sites,Edit" command group(s)\&. .SH "OPTIONS" .SS "Input section" .PP \fB\-sequence\fR \fIseqall\fR .RS 4 .RE .SS "Additional section" .PP \fB\-minlength\fR \fIinteger\fR .RS 4 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 .RE .PP \fB\-mismatches\fR \fIinteger\fR .RS 4 If there are this number or fewer contiguous non\-A bases in a poly\-A tail then, if there are \*(Aq\-minlength\*(Aq \*(AqA\*(Aq bases before them, they will be considered part of the tail and removed \&. For example the terminal 4 A\*(Aqs of GCAGAAAA would be removed with the default values of \-minlength=4 and \-mismatches=1 (There are not at least 4 A\*(Aqs before the last \*(AqG\*(Aq and so only the A\*(Aqs 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\*(Aqs preceding the last \*(AqG\*(Aq, so it is part of the tail\&. Default value: 1 .RE .PP \fB\-reverse\fR \fIboolean\fR .RS 4 When a poly\-T region at the 5\*(Aq 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 .RE .PP \fB\-tolower\fR \fItoggle\fR .RS 4 The poly\-A region can be \*(Aqmasked\*(Aq 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 \*(Aq\-supper\*(Aq sequence qualifier\&. Default value: N .RE .SS "Advanced section" .PP \fB\-fiveprime\fR \fIboolean\fR .RS 4 If this is set true, then the 5\*(Aq end of the sequence is inspected for poly\-T tails\&. These will be removed if they are longer than any 3\*(Aq poly\-A tails\&. If this is false, then the 5\*(Aq end is ignored\&. Default value: Y .RE .SS "Output section" .PP \fB\-outseq\fR \fIseqoutall\fR .RS 4 .RE .SH "BUGS" .PP Bugs can be reported to the Debian Bug Tracking system (http://bugs\&.debian\&.org/emboss), or directly to the EMBOSS developers (http://sourceforge\&.net/tracker/?group_id=93650&atid=605031)\&. .SH "SEE ALSO" .PP trimest is fully documented via the \fBtfm\fR(1) system\&. .SH "AUTHOR" .PP \fBDebian Med Packaging Team\fR <\&debian\-med\-packaging@lists\&.alioth\&.debian\&.org\&> .RS 4 Wrote the script used to autogenerate this manual page\&. .RE .SH "COPYRIGHT" .br .PP This manual page was autogenerated from an Ajax Control Definition of the EMBOSS package\&.
