Overview

BAS is a collection of perl modules that facilitate the development of perl scripts for bio-informatics applications. This document is a tutorial for BAS. In order to take advantage of BAS, all you have to do is change a few setup.

How to change a setup

Let's take an example. (1) Open the configuration file[BAS.conf]

        $ emacs BAS.conf 

• Following is contents of BAS

  ###############################################
  # Bacteria Analysis System configuration file>#

  #This is a configuration of Bacteria Analysis System
   
  package G::System::BAS_conf; 
   
  use strict("var"); 
   
  sub BAS{ 
    my $methods; 
   
    $methods= <<'CONF';

  G-instance      $gb
  
  -output                 #[f or stdout] default:"stdout"
  
  -w_output               #[f or stdout] default:"stdout"
  
  -w_filename

We have 10 classes and 24 methods.

• CAI
  • cai
• Codon
  • codon_counter
  • amino_counter
  • codon_usage
• Consensus
  • base_counter
  • base_information_content
  • base_z_value
  • base_entropy
  • base_relative_entropy
  • base_individual_information_matrix
• GCskew
  • view_cds
  • find_ori_ter
  • gcskew
  • genomicskew
  • cum_gcskew
  • gcwin
• Free Energy
  • foreach_RNAfold
• Markov
  • over_lapping_finder
• Over Lapping Gene
  • over_lapping_finder
  • Pat Search
  • palindrome
• Tandem Repeat
  • foreach_tandem
  • graphical_LTR_search
• Util
  • seq2gif
  • genome_map

(2) choose an analysis data

Default data is Escherichia_coli_K12. If you want to use another data, you have to change [gb1]. Also you can add a variable (ex.[mgen]).

• Before

    ##################################### 
    #  G instances                      # 
    #####################################   
    gb1 < /pub/dnadb/ncbi/genbank/genomes/bacteria/Ecoli/ecoli.gbk 

• After

    ##################################### 
    #  G instances                      #
    ##################################### 
  gb1 < /pub/dnadb/ncbi/genbank/genomes/bacteria/Ecoli/ecoli.gbk 
  mgen < /pub/dnadb/ncbi/genbank/genomes/bacteria/Mgen/mgen.gbk    # add 

(3) Choose a method

This time we use [codon_usage](codon class),for example.

・How to use [codon_usage]

１、First, turn [N] to [Y](this means switch on) and choose the analysis data at [G-instance]. If you want to put a output data into a file, change output option to [f]. You can find the file in [mgen]directory. And if you want to output a graph data, change output option to [g] (the graph is saved into [mgen/graph]). Default option [show] means show all results including graph and standard output results automatically.

-output	f	(put analysis data into a file)
	g	(output a graph analysis data)
	show	(show all analysis data automatically)
-filename	free	(using[-output] option, you can named filename)

• Before

  >codon_usage    N 
  G-instance      $gb 
  -CDSid 
  -output         show    #[f or g or show] default:"show" 
  -filename 

• After

  >codon_usage    Y       # switch on 
  G-instance      gb1     # choose data 
  -CDSid 
  -output         g       #[f or g or show] default:"show" 
  -filename 

1. save the file.

2. run the BAS

          $./BAS 

• Follwing is standard output results

1. output the graph

  $ cd mgen/graph 
  $ gimp codon_table.gif 

• If you want to put analysis data into a file.
• change output option to [f].
• save the file
• run the BAS.
• output the file

  $ cd mgen
  $ emacs codon_usage.csv 

• Following is standard output results

Notes

There is difference between [Essential] and [option]. [option] has [-] before option name(ex. -CDSid ), but [Essential] hasn't. You must to put variable into [Essential], but [option] is not.
