====== pluck_scripts ======

This is a set of Python scripts written by Kevin Karplus, originally created in /projects/lowelab/users/course/karplus (hence the acronym "pluck").  The scripts perform a variety of useful tasks.  Each one has minimal internal documentation, invoked by running with the --help option.
===== Scripts =====
  * check-hypotheses-with-solid given a set of hypotheses about possible changes to a scaffold, checks to see whether the SOLiD mate-pair reads provide more support for the original scaffold or the modified one.  The hypotheses are in the form  "AGT:contig00001 345:AGTA", that is, a string in the scaffold, where the string is located, and what the string is replaced with.  Either string can be "-" to represent an insertion or deletion. The insertion "-:contig00001 345:AA" would mean the insertion of two As before position 345 of contig00001, with numbering starting at 1 in the contig.
  * check-inversions FIXME
  * classify-blast-reads FIXME
  * extract-fragments FIXME
  * filter-blat FIXME
  * find-dna-differences compares a genome (or set of contigs) to a reference genome and reports differences in three formats: alignments of matching regions in a human-readable format, bed format for the location in the reference genome (loses some information about long insertions or replacements), and a short form that gives old_seq:reference location:new_seq for each change.  This program is only intended for small sets of differences, not for large rearrangements or distant relationships.  It may be buggy at the moment, as some of the Pog contigs that mapped completely to the genome were reported as not mapping (perhaps they were exact repeats?). 
  * find-frequent-color-kmers FIXME
  * kstitcher FIXME
  * make-contig-lengths FIXME
  * make-inversion-hypotheses FIXME
  * make-pseudoreads FIXME
  * make-scaffold-from-blat FIXME
  * map-colorspace FIXME
  * pair-contigs FIXME
  * select-by-color-kmers FIXME
  * tsv2gnuplot FIXME

===== Python modules =====
  * aligner.py  for doing local or global alignment.  This is a rather slow way to align things and should only be used for short sequences (like showing a small indel in context).
  * compress.py This was an attempt to merge color-space and flow space, by reducing all runs of 0s to a single 0.  It turned out not to be as useful as I'd hoped, and further exploration was abandoned. --- //[[karplus@soe.ucsc.edu|Kevin Karplus]] 2010/04/15 22:19//
  * fasta.py Input/Output module for fasta files, together with alphabet definitions and utility functions like reverse complement.
  * subst_matrix.py  for creating DNA substitution matrices from a small number of parameters.
