micalc - Performs basic mathematics with data sets

DESCRIPTION


micalc: Performs basic mathematics with data sets

File formats are automatically identified by their file extension. For binary
operations with two input files, the protocol of the first input file will be used
for the output file.

micalc can be used in one of the following modes:
Binary operation with data sets and/or scalar numbers:

micalc [-if1 <input-file1> | -in1 <input-number1>] -op
<operation(+,-,*,/,min,max,lcorr,kcorr)> [-if2 <input-file2> | -in2
<input-number1>] -of <output-file>

Accumulation of one data set:

micalc -if <input-file> -op <operation(+,*)>

Transformation (magnitude, logarithm, negation, inversion, or acos) of one data
set:

micalc -if <input-file> -op <operation(abs,log,-,/,acos)> -of <output-file>

Statistics of one data set:

micalc -if <input-file> [-mean <time-mean-file>] [-stdev <time-stdev-file>] [-fluct
<relative-time-stdev-file>] [-tcourse <average time course of all voxels>][-hist
<histogram> -histslots <numofslots> [-histmin <minval>] [-histmax <maxval>]
[-rightstairs] [-histfract] [-loghist] ]

into the array will result in a crash

Filters applied to input file(s) and mask:

an external file

in given range
