.SH NAME
roc\-at\-cutoff.pl \- computes ROC/sensitivity/specificity at various/all
thresholds
.SH SYNOPSIS
.IX Header "SYNOPSIS"
cbtest.pl <input1> [input2 ...]
.SH OPTIONS
.IX Header "OPTIONS"
Input file should be some alignment that has as a .rocr file
(presumably generated by filter.pl \-\-rocr). Output is graphed
to <basename>.cutoff.roc.png.
.PP
sensitivity/specificity requires a false negative count,
and as such requires a .filterstats file.
.PP
.Vb 10
\& Other options:
\&\-\-stat|predictor|x specifies what stat to use as a predictor
\&\-\-samples|n sets number of samples (default is sample at each possible cutoff)
\&\-\-maxsamples|maxn sets a max for n/samples
\&\-\-clean forces a re\-sampling of the .rocr file
\&\-\-log can apply log scale to x or y or xy axes
\&\-\-fn can specify a FN count for calculating sensitivity
\&\-\-avg preload averages (normally found from filterstats)
\&  (note: averages no drawn by default, so specify \-\-avg (with no args) to
\&   enable them)
\&\-\-noavg don\*(Aqt plot the line for averages
\&\-\-lwd can specify line weight
\&\-\-format can specify output file format (default png)
\&\-\-pdf set format to pdf
\&\-\-nofstats disable searching for filterstats statistics
\&\-\-nofn pretend not to have fn statistics (ie: skip sensitivity)
\&\-\-fstats specify the filterstats file to use
