.INPUT FILE: PIC001
[Enter the name of the image file to be remapped.]
.OUTPUT FILE: OUT001
[Enter name of output file where result is to be put.]
SPIDER will output the image range (FMIN ... FMAX) and
the offset used for normal display (=FMIN).]
.SCALING FACTOR: 3.5
[Density scaling factor by which each pixel will be
multiplied according to
TEMPPIXEL = (OLDPIXEL-OFFSET) * SCALE.
From this, the output is computed according to
NEWPIXEL = MOD(TEMPPIXEL,DIFF)
where DIFF is FMAX-FMIN for the image before re-scaling.]
.OFFSET: 0.15
[Enter offset constant, to be subtracted from the image
before rescaling. Unless you want to truncate part of the
density range, use 0.0]
