.SH OPTIONS
.SS Global Toolkit Options (these are shared by all CMTK tools)
.TP 5
\fB\-\-help\fR
Write list of basic command line options to standard output.
.TP 5
\fB\-\-help-all\fR
Write complete list of basic and advanced command line options to standard output.
.TP 5
\fB\-\-wiki\fR
Write list of command line options to standard output in MediaWiki markup.
.TP 5
\fB\-\-man\fR
Write man page source in 'nroff' markup to standard output.
.TP 5
\fB\-\-version\fR
Write toolkit version to standard output.
.TP 5
\fB\-\-echo\fR
Write the current command line to standard output.
.TP 5
\fB\-\-verbose-level\fR \fI<integer>\fR
Set verbosity level.
.TP 5
\fB\-\-verbose\fR, \fB\-v\fR
Increment verbosity level by 1 (deprecated; supported for backward compatibility).
.TP 5
\fB\-\-threads\fR \fI<integer>\fR
Set maximum number of parallel threads (for POSIX threads and OpenMP).
.SS Main Options
.TP 5
\fB\-\-radius\fR \fI<double>\fR, \fB\-r\fR \fI<double>\fR
Radius of spheres to detect in physical length units (typically mm).
.B [Default: 1]
.TP 5
\fB\-\-filter-margin\fR \fI<integer>\fR
Half of filter margin width in pixels. This determines the extent of the region around the surface or the sphere where the detection filter is non-zero.
.B [Default: 2]
.TP 5
\fB\-\-normalized\fR
Use intensity-normalized filter, effectively computing Normalized Cross Correlation between filter and image.
