NAME

micalc - Performs basic mathematics with data sets

DESCRIPTION

micalc: Performs basic mathematics with data sets
File formats are automatically identified by their file extension.

Usage:

Binary operation with data sets and/or scalar numbers:
micalc [-if1 <input-file1> | -in1 <input-number1>] -op <operation(+,-,*,/,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 <time-course of all voxels>] [-hist <histogram> -histmin <minval> -histmax <maxval> -histslots <numofslots> -rightstairs -histfract]

-mask <Mask for data>

-cplx: Treat data as complex and extract the given component (options=none abs pha real imag , default=none)
-ds: Dataset index to extract if multiple datasets are read
-filter: Read only those datasets which protocol parameter 'key' contains the string 'value' (given in the format 'key=value')
-fmap: For reduced memory usage, keep filemapping after reading (raw) data, but writing into the array will result in a crash
-jdx: If multiple JDX arrays are present, select this
-rdialect: Read data using given dialect of the format. (default is no dialect)
-rf: Read format, use it to override file extension (options=autodetect 3db asc coi dat dcm double float gz hdr ima jdx mag mhd nii ph png pos reg s16bit s32bit s8bit smp u16bit u32bit u8bit v vtk , default=autodetect)
-skip: Skip this amount of bytes before reading the raw data (default=0)

File write options:

-append: Append to existing file, only for raw data
-split: Force splitting of protocol-data pairs into separate files.
-type: Image representation type (options=automatic float double s32bit u32bit s16bit u16bit s8bit u8bit , default=automatic)
-wdialect: Write data using given dialect of the format. (default is no dialect)
-wf: Write format, use it to override file extension (options=autodetect 3db asc coi dat dcm double float gz hdr ima jdx mag mhd nii ph png pos reg s16bit s32bit s8bit smp u16bit u32bit u8bit v vtk , default=autodetect)
-wp: Store the protocol separately to this file.

Filters applied to input files:

-align <filename,In-plane blowup factor> : Align data to the geometry (voxel locations) of an external file
-detrend <Number of low frequency components to be removed> : Remove slow drift over time
-genmask <lower threshold,upper threshold> : Create mask including all voxels with value in given range
-isotrop <voxelsize> : make image voxels isotrop through interpolation (image geometry will not change)
-max <Maximum value> : Clip all values above maximum value
-merge : Merge datasets into a single dataset by expanding the time dimension
-min <Minumum value> : Clip all values below mininum value
-noNaN <Replacement value> : Replaces every NaN by the given value
-pflip : Flip data in phase direction
-prange <Single value or range, optionally with increment (e.g. 1-10:3)> : Select range in phase direction
-resize <slice-size,phase-size,read-size> : Resize image data
-reslice <requested orientation (sagittal coronal axial )> : reslices the image to a given orientation
-rflip : Flip data in read direction
-rot <angle [deg],kernel size [pixel]> : In-plane rotation
-rrange <Single value or range, optionally with increment (e.g. 1-10:3)> : Select range in read direction
-scale <Slope,Offset> : Rescale image values
-sflip : Flip data in slice direction
-shift <readDirection shift [pixel],phaseDirection shift [pixel],sliceDirection shift [pixel]> : Shift data spatially
-splice <dimension of the data to be spliced (time slice phase read none )> : splices the image in the given dimension
-srange <Single value or range, optionally with increment (e.g. 1-10:3)> : Select range in slice direction
-swapdim <[rps][-],[rps][-],[rps][-]> : swap/reflect dimensions by specifying a direction triple with optional reflection sign appended
-tile <columns> : Combine slices into a square 2D image
-trange <Single value or range, optionally with increment (e.g. 1-10:3)> : Select range in time direction
-typemax <Datatype> : Clip all values above maximum of a specific datatype
-typemin <Datatype> : Clip all values below mininum of a specific datatype
-usemask <filename> : Create 1D dataset using mask from file

Other options:

-v <loglevel> or <component:loglevel> for debugging/tracing all components or a single component, respectively. Possible values for loglevel are: 0(noLog), 1(errorLog), 2(warningLog), 3(infoLog), 4(significantDebug), 5(normalDebug), 6(verboseDebug).

Voici que revient le printemps et ses effets dévastateurs sur le métabolisme des grands mammifères. L'un d'entre eux, que nous appellerons Paul, Émile, Victor, qu'importe, se releva une nuit dans un état de grande excitation, pensant pouvoir assouvir ses pulsions par le biais d'un des nombreux sites pornographiques disséminés sur la toile.
Malheureusement pour lui, son fournisseur d'accès - comme c'était d'ailleurs trop souvent le cas - s'avéra injoignable cette nuit-là et, seul et désespéré, il dut se résigner à retrouver son lit où il demeura jusqu'au petit matin sans trouver le sommeil.
Moralité : En rut, connexion à la noix en nocturne.
