SLiMSuite release 2014-08-25 now available

A new download of SLiMSuite (release 2014-08-25) is now available (svn r466).

The latest release sees a major revamp of the basic chassis for SLiMSuite onto a newer underlying SLiMCore 2.x class to enable the megaslim=FILE upgrade (below). This should have no effect on end use but please report any odd behaviour, as it is possible that some compatibility bugs have crept in that will crash programs in rare scenarios.

The following tools are now in ./legacy/:

slimsuite/legacy/gopher_V2.py
slimsuite/legacy/qslimfinder_V1.9.py
slimsuite/legacy/slimbench_V1.py
slimsuite/legacy/slimdisc_V1.4.py
slimsuite/legacy/slimfinder_V4.9.py
slimsuite/legacy/slimprob_V1.4.py

SLiMSuite now features a new mode for multiple runs/datasets featuring the same input proteins. Running with megaslim=FILE, where FILE is a fasta file of all possible sequences in the dataset(s), will generate files of masking scores that can be reused instead of recalculating each time. In each case, each sequence will be on one line, with the sequence name followed by a score per residue. If dismask=T then *.iupred.txt or *.anchor.txt will be created/read, which will list the disorder score for each position. If consmask=T then *.rlc.txt will list RLC scores. By default, scores will be read where present, or calculated and appended where missing. Running rje_slimcore will calculate all sequences for megaslim=FILE.

In addition to disorder and conservation scores, running SLiMCore with megablam=T will also create an all-by-all GABLAM run, which can be used for subsequent UPC generation. Even without megaslim=FILE, this can still be used with the gablamdis=FILE option.

If megaslim=None (the default), creating alignments for conservation masking can also be sped up giving usegopher=T gopherdir=PATH forks=X, where forks > 1. This will use forking to check/create GOPHER alignments for all input sequences before a regular masking run.

The final upgrade of note is that SLiMBench now features an occurrence benchmarking mode (occbench=T), which has not yet made its way into the manual. More on SLiMBench soon.

Bug fixes in this release:

• Combined case masking and disorder masking bug fixed.
• Minor bugs (introduced with DNA=T mode) that affect extended alphabets in SLiMFinder have been fixed.
• A minor bug in SLiMProb that returned position 0 to L-1 rather than 1-L for N-terminal motif matches (^xxx) has been fixed.
• A bug affecting GOPHER when run with rje_blast_V2 has been fixed. There might still be some issues with rje_blast_V2 when number of alignments output is smaller than the number of one-line hits.
