Belvu - View multiple alignments in pretty colours.
Usage: belvu [options] <multiple_alignment>|-
<multiple_alignment>|- = file or pipe in Stockholm/Selex/MSF/Fasta format (see below).
Options:
-c Print Conservation table.
-l <file> Load residue color code file.
Format: <symbol> <color>
(Lines starting with # are ignored (comment lines))
Example of color code file:
# Aroma
F YELLOW
Y YELLOW
W YELLOW
# Yuck
D RED
N GREEN
X BLUE
Available colors:
WHITE
BLACK

-L <file> Load markup and organism color code file.
Colour the markup text by residue or colour organism in tree.
Example to set color of letters A and B:
A GREEN
B YELLOW
Example to set color of organism human:
#=OS BLUE human
-m <file> Read file with matching sequences segments. This is used to
display a match of a query sequence to a family. The format
of the match is :
Line 1: Name/start-end score
Line 2: Query sequence in matching segment, no pads!
Line 3: Sequence of matching segments (qstart1 qend1 fstart1
fend2 qstart2 qend2 fstart2 fend2 etc...).
Example:
ZK673.9/238-260 21.58
CPENWVQFTGNGTQYGVCLRGFT
1 2 1 2 4 7 8 11
NOTE: A sometimes easier way of doing this is to concatenate
the match to the end of the alignment, after a line with
exactly this string within the quotes: # matchFooter
-r Read alignment in 'raw' format (Name sequence).
Example of raw alignment file:
seq1_name MFILKTP
seq1_name MYI.RTP
-R Do not parse coordinates when reading alignment.
-o <format> Write alignment or tree to stdout in this format and exit.
Valid formats: Mul(Stockholm), Selex, MSF,
FastaAlign, Fasta, tree.
-X <cutoff> Print UPGMA-based subfamilies at cutoff <cutoff>.
-n <cutoff> Make non-redundant to <cutoff> %identity at startup.
-Q <cutoff> Remove columns more gappy than <cutoff>.
-q <cutoff> Remove sequences more gappy than <cutoff>.
-G Penalize gaps in pairwise comparisons.
-i Ignore gaps in conservation calculation.
-P Remove partial sequences at startup.
-C Don't write coordinates to saved file.
-z <char> Separator char between name and coordinates in saved file.
-a Show alignment annotations on screen (Stockholm format only).
-p Output random model probabilites for HMMER.
(Based on all residues.)
-S <order> Sort sequences in this order.
a -> alphabetically
o -> by Swissprot organism, alphabetically
s -> by score
n -> by Neighbor-joining tree
u -> by UPGMA tree
S -> by similarity to first sequence
i -> by identity to first sequence
-s <file> Read in file of scores.A column with scores will
automatically appear after the coordinates.
Format: <score> <sequence_id>
Example of score file:
2.78 seq_1/180-206
2.78 seq_2/180-206
3.79 seq_3/42-94
-T <method> Tree options:
i -> Start up showing tree
I -> Start up showing only tree
d -> Show distances in tree
n -> Neighbor-joining
u -> UPGMA
c -> Don't color tree by organism
o -> Don't display sequence coordinates in tree
b -> Use Scoredist distance correction (default)
j -> Use Jukes-Cantor distance correction
k -> Use Kimura distance correction
s -> Use Storm & Sonnhammer distance correction
r -> Use uncorrected distances
p -> Print distance matrix and exit
R -> Read distance matrix instead of alignment
(only in combination with Tree routines)
-b <n> Apply boostrap analysis with <n> bootstrap samples
-B Print out bootstrap trees and exit
(Negative value -> display bootstrap trees on screen)
-O <label> Read organism info after this label (default OS)
-t <title> Set window title.
-u Start up with uncoloured alignment (faster).
-h, --help Show this help information
--compiled Show package compile date
--version Show package version number
setenv BELVU_FETCH to desired sequence fetching program.
setenv BELVU_FONT_SIZE to specify window font size.
setenv BELVU_STATUSBAR_SIZE to specify statusbar font size (0 => hide statusbar).
