Hello Sdanner and Steadyonabix,
I have tried to come up with an easier way to describe what I need to do with my file. If you recall I have a file that looks like this:
ID 1 2 3 4 5 6 7 8
83845676 0 0 0 0 CC -1 CC CC
838469. -1 -1 1 GG CC 0 CC 1
83847041 -1 . 0 0 . 0 0 0
83847.4 0 -1 1 1 CC 0 0 0
83847085 0 CC 0 0 0 0 0 0
83847118 . -1 1 GG . GG CC 0
83847162 GG -1 1 0 0 0 0 0
83847165 -1 -1 . GG CC 0 GG 0

I have to get everything recoded for a specific program that only recognizes -1, 0, and 1 but the CC and GG cause an issue because they can take on multiple values. Perhaps calculating the minimum and maximum of each column may be easier (?)....

When min = -1 and max = 0, then both CC and GG = 1;
When min = 0 and max = 1, then both CC and GG = 1;
When both the min and max = 0, then CC = -1 and GG = 1;

I hope this clears things up a bit! Any help you could provide would be GREATLY appreciated!

Thanks,
Doob

mlib_imageextrema2_fp

mlib_ImageExtrema2(3MLIB)				    mediaLib Library Functions					 mlib_ImageExtrema2(3MLIB)

NAME

       mlib_ImageExtrema2, mlib_ImageExtrema2_Fp - image extrema

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status  mlib_ImageExtrema2(mlib_s32  *min,	mlib_s32  *max, const mlib_image *img, mlib_s32 xStart, mlib_s32 yStart, mlib_s32 xPeriod,
       mlib_s32 yPeriod);

       mlib_status mlib_ImageExtrema2_Fp(mlib_d64 *min, mlib_d64 *max, const mlib_image *img, mlib_s32 xStart, mlib_s32 yStart, mlib_s32  xPeriod,
       mlib_s32 yPeriod);

DESCRIPTION

       Each of the functions determines the extrema values for each channel in an image, possibly with subsampling.

       It uses the following equation:

       min[i] = MIN{ img[x][y][i] }
       max[i] = MAX{ img[x][y][i] }

       where

       x = xStart + p*xPeriod;	0 <= p < (w - xStart)/xPeriod
       y = yStart + q*yPeriod;	0 <= q < (h - yStart)/yPeriod

PARAMETERS

       Each of the functions takes the following arguments:

       min	       Pointer to minimum vector, where length is the number of channels in the image.	min[i] contains the minimum of channel i.

       max	       Pointer to maximum vector, where length is the number of channels in the image.	max[i] contains the maximum of channel i.

       img	       Pointer to a source image.

       xStart	       Initial X sample coordinate.

       yStart	       Initial Y sample coordinate.

       xPeriod		X sample rate.	xPeriod >= 1.

       yPeriod		Y sample rate.	yPeriod >= 1.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

ATTRIBUTES
