NAME

       squizz - Sequence format checker

SYNOPSIS

       squizz [-AShlns] [-c format] [-f format] file

OPTIONS

       Following command line options are allowed:

       -A  Restrict detection/verification to alignment formats (conflict with -S option).

       -S  Restrict detection/verification to sequence formats (conflict with -A option).

       -c format
	   Convert detected sequence/alignment into format. This option implies strict alignment checking.

       -f format
	   Assume input format is format. Do not try to detect the format, just verify that the given one is correct.

       -h  Usage display.

       -l  List all supported formats.

       -n  Count and report detected entries. This option is only available when the detection is restricted to a single type (with -A or -S
	   options) and strict checks (without -s option) are enabled.

       -s  Disable strict format checks (enabled by default).

DESCRIPTION

       squizz is a sequence format file checker, but it has some conversion capabilities too.

       squizz can detect the most common sequence and alignment formats :

       * EMBL, FASTA, GCG, GDE, GENBANK, IG, NBRF, PIR (codata), RAW, and SWISSPROT.

       * CLUSTAL, FASTA, MSF, NEXUS, PHYLIP (interleaved and sequential) and STOCKHOLM.

       squizz can do some conversions too, if the format the input format is supported. Only 3 types are available : sequence to sequence, align-
       ment to alignment, and alignment to sequence (the last one, sequence to alignment, require multiple alignments algorithms and cannot be
       handled with formatting tools).

       Strict format checks validate the previously detected objects, by making some sanity checks:

       - sequence strings must exists.
       - alignment is made of more than one sequence.
       - alignment sequence strings must have the same length.
       - alignment sequence names must exists, and be unique.
