This module is primarily to contain core dataset processing methods for both SLiMFinder and SLiMProv to inherit and use. This primarily consists of the options and methods for masking datasets and generating UPC. This module can therefore be run in standalone mode to generate UPC files for SLiMFinder or SLiMProb. It can also be used to generate "MegaSLiM" files of precomputed scores that can be used for subsequent subdata.

In addition, the secondary MotifSeq and Randomise functions are handled here.

Secondary Functions

The "MotifSeq" option will output fasta files for a list of X:Y, where X is a motif pattern and Y is the output file.

The "Randomise" function will take a set of input datasets (as in Batch Mode) and regenerate a set of new datasets
by shuffling the UPC among datasets. Note that, at this stage, this is quite crude and may result in the final
datasets having fewer UPC due to common sequences and/or relationships between UPC clusters in different datasets.

The "EquivMaker" function will read in a BLOSUM matrix and, for a particular score cut-off, generate all equivalence
groups for which all members have pairwise BLOSUM scores that equal or exceed the cut-off. This equivalence file can
then be used as input for TEIRESIAS or SLiMFinder.

SLiMCore REST Output formats

Run with &rest=help for general options. Run with &rest=full to get full server output as text or &rest=format
for more user-friendly formatted output. Individual outputs can be identified/parsed using &rest=OUTFMT for:

disorder = List of predicted disorder scores for proteins (if consmask=T or using special disorder rest call)
rlc = List of RLC scores for proteins (if consmask=T or using special rlc rest call)
upc = Groupings of unrelated proteins (if efilter=T)

Note that SLiMCore can either be run as or special runs can be used to
try and directly access RLC or Disorder scores for an individual protein:

If these data already exist, they will be returned directly as plain text. If not, a jobid will be returned,
which will have the desired output once run.
