Perl 如何将PHYLIP格式转换为FASTA,perl,bioinformatics,Perl,Bioinformatics,我刚开始使用perl，我有一个问题。我有PHYLIP文件，我需要将其转换为FASTA。我开始写剧本。首先，我删除了行中的空格，现在我需要对齐所有行，每行中应该有60个氨基酸，序列标识符应该打印在新的行中。也许有人能给我一些建议？BioPerl模块可能会有所帮助。它支持序列格式： phylip2fasta.pl use strict; use warnings; use Bio::AlignIO; # http://doc.bioperl.org/bioperl-live/Bio/AlignI

我刚开始使用perl，我有一个问题。我有PHYLIP文件，我需要将其转换为FASTA。我开始写剧本。首先，我删除了行中的空格，现在我需要对齐所有行，每行中应该有60个氨基酸，序列标识符应该打印在新的行中。也许有人能给我一些建议？

BioPerl模块可能会有所帮助。它支持序列格式：

phylip2fasta.pl

use strict;
use warnings;
use Bio::AlignIO; 

# http://doc.bioperl.org/bioperl-live/Bio/AlignIO.html
# http://doc.bioperl.org/bioperl-live/Bio/AlignIO/phylip.html
# http://www.bioperl.org/wiki/PHYLIP_multiple_alignment_format

my ($inputfilename) = @ARGV;
die "must provide phylip file as 1st parameter...\n" unless $inputfilename;
my $in  = Bio::AlignIO->new(-file   => $inputfilename ,
                         -format => 'phylip',
                         -interleaved => 1);
my $out = Bio::AlignIO->new(-fh   => \*STDOUT ,
                         -format => 'fasta');

while ( my $aln = $in->next_aln() ) {
    $out->write_aln($aln);
}

$perl phylip2fasta.pl test.phylip

如果您可以访问BioPerl，我建议您使用它（参见其他答案）。如果没有，下面是我几年前在一个旧的硬件作业中使用的一个快速脚本。它可能对你有用

需要注意的一点是：它在一行上打印整个fasta序列，因此您必须编辑最后的打印语句，以便每行打印70 AA

#!/usr/bin/perl

use warnings;
use strict;

<DATA> =~ /(\d+)/; # first number is number of species

my $num_species = $1;
my $i = 0;
my @species;
my @acids;

# first $num_species rows have the species name
for ($i = 0; $i < $num_species; $i++) {   
    my @line = split /\s+/, <DATA>;
    chomp @line;

    push @species, shift (@line);
    push @acids, join ("", @line);

}

# Get the rest of the AAs
$i = 0;
while (<DATA>) {
    chomp;
    $_ =~ s/\r//g; #remove \r

    next if !$_;

    $_ =~ s/\s+//g; #remove spaces
    $acids[$i] .= $_;
    $i = ++$i % $num_species;

}

# Print them
for ($i = 0; $i < $num_species; $i++) {
    print "> ", $species[$i], "\n";

    # uncomment next line if you want to remove the gaps ("-")
    $acids[$i] =~ s/-//g;
    print $acids[$i], "\n\n";
}

我认为doc.bioperl.org网站需要一些工作。与…相比。我想这应该是意料之中的，因为生成它的代码从那以后就没有更新过。谢谢你的anser，但是没有bioperl我怎么能做到呢？只是出于好奇，为什么你需要转换成fasta，它是否与你需要的fasta对齐。
