SETPREPROC

Set the PREPROC field of a datafile

    A = SETPREPROC(A,PREPROC,PARS)
    A = SETPREPROC(A,PSTRUCT)
    A = SETPREPROC(A)

Input
A	Datafile
PREPROC	String with preprocessing command
PARS	Cell array with parameters (default empty)
PSTRUCT	Structure array with a set of preprocessing commands

Output
A	Datafile

Description

Resets the structure array of preprocessing commands in A.PREPROC.  A.PREPROC(N).PREPROC = PREPROC A.PREPROC(N).PARS = PARS

A call without PREPROC and PARS clears A.PREPROC.

Preprocessing can only be defined for raw datafiles that do not contain  datasets. It is an error to define preprocessing for a datafile that  points to MAT files. In that case datasets are expected and preprocessing  is superfluous. All preprocessing commands are executed just before a  DATAFILE is converted into a PRDATASET.

The first command in the PREPROC field should always be a file read  command. The DATAFILE constructor stores by default IMREAD. It is removed  by SETPREPROC. Be sure to start a new series of preprocessing commands by  a command to read files. The first parameter of this commands should be  the filename.

Additional preprocessing commands may be stored by ADDPREPROCC.
