Package for simplify MAPP prediction analysis workflow.
This package servers to simplify workflow of MAPP program.
You have to install:
- Python 2.7
- MAPP program.
- Optionally download fasta database (or it is possible to use HMMER or BLAST program remotely).
- Install program for sequence searching. Recommended is HMMER. Or it is possible to download BLAST.
- Install multiple sequence alignment program (recommended is MAFFT).
- Install phylogenetic tree construction program (recommended is FastTree).
- Install Biopython package (if you want to use file convert tools).
For MAPP analysis settings file is needed (in python ConfigParser syntax).
Settings file contains commands and input/output of commands. One command should be one basic shell command (semicolon etc. are not allowed).
Settings file could be easilly created by another script and then is easy to run multiple mapp analysis at once.
Basic and minimal required structer for settings.conf is:
[commands] #id used for name of analysis id= #sequence file in fasta format sequence = #output file from blast or hmmer program blastout = #file where programs store stats about sequence picking blaststat = # blast command to run blast = # input file for multiple sequence aligning program (same as blast output) msain = %(blastout)s # msa program output file msaout = # this command is executed before msa program is executed # (it could be for blast output conversion and purifying) beforemsa = # msa program command msa = # tree program input file (converted msaout file to newick format) treein = # tree program output file treeout = # this command is executed before the tree program beforetree = # tree program command tree = # mapp program input msa file (in fasta format - could be the same as msaout value) mappinmsa = # mapp program input tree file (in newick format) mappintree = # mapp program output file mappout = # command before the mapp command (good for e.g. adjust tree to proper newick format) # MAPP is really sensitive to proper file format beforemapp = # MAPP command itself mapp = java -jar MAPP.jar -f %(mappinmsa)s -t %(mappintree)s -o %(mappout)s
Basic usage in python program
Basic python code:
from mapp.core.analyzers import Analyzer from mapp.core.parsers import SettingsParser from mapp.core.exceptions import MappError settings_file = 'settings.conf' def main(): try: mapp = Analyzer(SettingsParser(settings_file)) mapp.exec_mapp() except MappError as e: print(e.header) print(e.description) if __name__ == '__main__': main()
In the mapp.utils package are files that can be use as standalone scripts or as modules. This file mostly serves for file conversions and purifying.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
