LIPSIA     Extract one time step from an fMRT time series
vtimestep
The program 'vtimestep' extracts one time step from an fMRT data set and prepares it for visualization. It can be used to diagnose geometric distortions of registration errors.

Here is an example:

vtimestep -in infile.v -out outfile.v -step 0

The input into 'vtimestep' is an fMRT data set. It can either be a raw data set or a processed data set (i.e. processed by 'vpreprocess' or 'vfunctrans'). The output is a single time step represented as a 3D data set. It can be visualized using 'vlview' .

The parameter '-step' specifies the time step to be selected. Indexing starts at '0'.

The parameter '-repn' denotes the output representation type. If set to 'ubyte' then it can be easily visualized using 'vlview' or ' 'vlv'.

Parameters of 'vtimestep':
-help
Prints usage information.
-in
Input file. Default: (none)
-out
Output file. Default: (none)
-step
Time step to be extracted. Default: 0
-repn [ ubyte | short | float]
Output representation type. Default: ubyte
