Hello all,
I'm very new to Python and have been trying to write a script to compare data from 2 files and getting a total. One of the two files contains x, y positions of pixels and a color value(z) of each, so it has three columns in the file. The other file has two columns; x1, y1. I'd like to get only x, y positions which match to x1, y1 of the second file and then look up the z value. If the z value is greater than a certain number, it counts 1, otherwise it moves on the next x, y position. Finally, I'm able to get total count of the pixels that are over the threshold. The script I'm using is below step by step, however, I haven't been able to figure out the error massage "IndexError: list index out of range" on z value. Any comments would be appreciated!
Regards, Michiyo

while line:

x1=fields[0, 1] in i #x,y position in file 1

if x1 == x2: read(z)

print>>l, count(1)
i.close() o.close() l.close()
