NAME
miget_slice_min - get the minimum real value of the slice
SYNOPSIS
#include <minc2.h>
int miget_slice_min ( mihandle_t volume,
unsigned long start_positions[],
unsigned long array_length,
double *slice_min)
DESCRIPTION
This method returns the slice_min with the minimum real value of
the corresponding slice. Note that this function is not defined
for floating point data type nor it works if the volume is globally scaled.
RETURN VALUE
miget_slice_min returns MI_NOERROR if it successfully returns the slice_min
or MI_ERROR otherwise
