# DomPred code that
# read-in arguments from Java code
# output results page
# and alot more between
#
# Modification Record
# 23/02/2004 R. Marsden Created.
# 30/04/2004 K. Bryson Added configuration parameters so that the
# script can be used for a 'stand-alone' test-bed.
# 10/05/2004 K. Bryson Fixed output problem for 'Putative domain boundaries' table.
# 10/05/2004 K. Bryson Fixed scale problem on graph
# (normalized smhash values used, not plothash values,
# so biggest_plothash value should no longer be used).
# 14/05/2004 K. Bryson Fixed formatting problem for domain boundaries in the DomSSEA
# results table (re-positioned <TD>..</TD> tags).
# Eliminated output of empty rows when number of hits is less than 10.
# 14/05/2004 K. Bryson Commented out tests on alpha/beta content for the query/match sequences.
# According to Liam these are not needed for DomSSEA output.
# 19/05/2004 K. Bryson Output of DPS multi-domain boundaries in ascending order.
# Output boundary predictions by DomSSEA which are close to
# the N-/C-termini as values in red, rather than '?' symbols.
# Changed the 'flattening' around detected boundaries from +/-20aa to +/-40aa.
# 20/05/2004 K. Bryson Output overall summary of predictions by DPS, even when only 1 domain is predicted.
# This simplifies parsing of the results for the email server and also
# clarifies the overall result produced by DPS for a novice user.
# 28/05/2004 K. Bryson Changed 'flattening' to be +/- 80aa now.
# Fixed bug in output of number of domains
# (Uses $num_peaks now instead of $peaks_detected).
# 04/06/2004 K. Bryson Added configurational parameter for the database used.
# Created a new uniref90_Pfam_A_nofrag database.
# 07/06/2004 K. Bryson After examining the results of some benchmarking,
# put back the old database ! Probably optimally configured for this.
# 07/06/2004 K. Bryson Extended the end-effect flattening to +/-70aa (plus another 10aa possibly ?).
# 15/06/2004 K. Bryson Added '0' to pdb identifiers for SCOP file indexing.
# 17/06/2004 K. Bryson Fixed bug calculating the variance in the z-score section (crashed CASP6 T203 target).
# TEMP FIX - Just take the abs(variance) value --- using the correct value
# 'throws out' all the other calibration and domain prediction becomes unreliable.
# 17/06/2004 K. Bryson Sorted problems with graphing code (flattening smhash, using '-' instead of 0).
# 17/06/2004 K. Bryson Tidied up code by removing completely unused sections of code.
# 17/06/2004 K. Bryson Took out 'helix' and 'strand' profiles from graph since these are distracting from
# the real graph of aligned termini profile and are undocumented in the help file.
# Replaced them with raw output of helix and sheet regions as points, similar to that for coil.
# This is cleaner, less distracting, and provides similar information for domain prediction.
# 18/06/2006 K. Bryson Updated for CASP7 to use the latest uniref90_PfamA databsae.
#
# 06/04/2008 D. Buchan Additionally added an output file for the DOMssea lines that are selected
# Took out that nonsense of wrapping the blast files in <pre> tags so that they are "html"
# (note that .blastdom and blast.bls are identical. blast.bls is then gzipped for passing into the
# rails db).
# Changed the output image to a 16bit png and removed the use of jpegtran. The image is now rotated
# by mogrify in a single rescaling and rotating step. The png is clearer. it might be worth
# playing with the rescaling filter to make the image look nicer.
# Added a couple of output flat files - .boundary for the DPS info
# .domsseatable for the domssea results that will be reported on the webpage
# Removed all code that writes out to any html files. This should be handled by the view in Rails not at the backend.
# PSI-Blast is no longer run within this script, the rails backend now handles this (possible candidate for command line switch though).
# Added too many commandline options to remove any hardcoded paths.
#
##################################
#
# TODO:
# Suppress the calls to gs mogrify and have the java backend run those - annoyingly it does all sorts of stuff about testing
# where the ps and png images are which would also need to be written out.
# Have the input data for the gnuplots output to files and have the java backend run gnuplot
#
# add -w and use strict and fix all runtime errors, see parseDS_fixattempt.pl
