sequence
Input query sequence.
This DNA or protein sequence will be used to search for matches to a library of PROSITE profiles.
The content of the file must be either in EMBL/SWISS-PROT (default) or in Pearson/Fasta format
(option -f). If the filename is replaced by a '-', pfscan will read the input sequence from
stdin.
profile_library
Library of PROSITE profiles.
This file should contain one or several PROSITE profiles, against which the query sequence will be
matched. Each entry in this library should be separated from the next by a line containing only
the '//' code. If the filename is replaced by a '-', pfscan will read the profile library from
stdin.
-a Report optimal alignment scores for all profiles regardless of the cut-off value. This option
simultaneously forces DISJOINT=UNIQUE.
-b Search the complementary strand of the DNA sequence as well.
-f Input sequence is in Pearson/Fasta format.
-h Display usage help text.
-l Indicate the value of the highest cut-off level exceeded by the match score in the output list.
-L Indicate by character string the highest cut-off level exceeded by the match score in the output
list.
Note: The generalized profile format includes a text string field to specify a name for a cut-off
level. The -L option causes the program to display the first two characters of this text
string (usually something like '!', '?', '??', etc.) at the beginning of each match
description.
-m Report individual matches for circular profiles.
If the profile is circular, each match between a sequence and a profile can be composed of a
stretch of individual matches of the profile. By default, pfscan reports only the total matched
region. When this option is set, detailed information for each individual match will be output as
well.
Note: The scoring system for most circular profiles has been optimized to find total matches,
therefore the normalized scores of individual matches of a circular profile to a sequence
should be considered with caution.
-r Use raw scores rather than normalized scores for match selection. The normalized score is not
printed.
-u Forces DISJOINT=UNIQUE.
-Ccut_off
Cut-off level to be used for match selection.
The value of 'cut_off' should be the numerical identifier of a cut-off level defined in the
profile. The raw or normalized score of this level will then be used to include profile to
sequence matches in the output list.
If the specified level does not exist in the profile, the next higher (if cut_off is negative) or
next lower (if cut_off is positive) level defined is used instead.
Type: integer
Default: 0
-Mmode_nb
Normalization mode to use for score computation.
The 'mode_nb' specifies which normalization mode defined in the profile should be used to compute
the normalized scores for profile to sequence matches. This option will override the profile's
PRIORITY parameter.
If the specified normalization mode does not exist in the profile, an error message will be output
to standard error and the search is interrupted.
Type: integer
Default: lowest priority mode defined in the profile
Outputmodifiers-d Limit profile description length.
If this option is set, the description of the profile on the header line will be limited in
length. If the match information is longer than the output width specified using option -W, the
profile description will not be printed. Else the description will be truncated to fit the -W
value.
By default, the profile description is not truncated. This option can not be used when option -k
is set.
-k Use xpsa(5) headers for output.
When this option is set, all output types (see below) will use an xpsa(5) style header line. This
format uses keyword=value pairs to output alignment parameters. It is useful to transfer
information between different sequence alignment tools.
-s List the sequences of the matched regions as well. The output will be a Pearson/Fasta-formatted
sequence library.
-v Suppress sequence/profile parsing warnings. If this option is set no warning messages will be
printed on stderr. Only fatal errors will be reported. This option should be used with caution.
-x List profile-sequence alignments in psa(5) format. Please refer to the corresponding man page for
more information.
-y Display alignments between the profile and the matched sequence regions in a human-friendly
pairwise alignment format.
-z Indicate starting and ending position of the matched profile range. The latter position will be
given as a negative offset from the end of the profile. Thus the range [ 1, -1] means entire
profile.
-Wwidth
Set alignment output width.
The value of 'width' specifies how many residues will be output on one line when any of the
-s, -x or -y options is set.
Type: integer
Default: 60
