Image analysis does not work

During my time in the USA as a visiting scientist I started working with MatLab R2007a. Now I am back in my group I want to use the same m-files, but we only have MatLab R2010b. Using the m-files I used in USA results everytime in an error. I sent the images to our colleges in USA and they tried to let them run with their MatLab version. There it works.
Is there a huge difference between using m-files in different MatLab versions?
One part of the error called: "nrm". Have anyone seen such an error before and can give me a hind for what nrm stands for?
Thanks a lot

In particular, tell us specifically what error messages are shown. It is possible that there were some upgrades to the MATLAB core or toolboxes between R2007a and R2010b that are breaking your scripts.

Undefined function or method 'nrm' for input arguments of type 'double'.
The program is trying to call a function called nrm, but it cannot find it. It doesn't seem to be a standard MATLAB function in any toolboxes that I have (and I cannot find a reference to it on the web). Maybe it is something your colleagues wrote (or downloaded). Maybe it is a function you have, but haven't set the path correctly.

In addition do Daniel's answer, I'd like to suggest you ask your colleagues to run:
which nrm -all
then send you the (possibly) missing function.

At first I was going to comment that this won't return anything. Then I saw the "colleagues" part. Maybe you can bold that ...

I would recommend checking the release notes to see what has changed:
Or you could use:
dbstop if error
to make MATLAB stop when you recieve an error so you can see what isn't working.
