第一大坑，signalP
解压这个包之后，莫名其妙报错

./signalp -t euk -f short test/euk10.fsa > euk10.fsa.short_out
Can't locate FASTA.pm in @INC (you may need to install the FASTA module) (@INC contains: /usr/cbs/bio/src/signalp-4.1/lib /home/huangle/perl5/lib/perl5/5.22.1/x86_64-linux-gnu-thread-multi /home/huangle/perl5/lib/perl5/5.22.1 /home/huangle/perl5/lib/perl5/x86_64-linux-gnu-thread-multi /home/huangle/perl5/lib/perl5 /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at ./signalp line 80.

原来是不知道signalP的本地包在哪里。
查了readme里面什么都没有，一打开源码才知道里面有一个customize的部分：
