When you get an error message that reads like this:
Error: File: FinProject_ImgAlign.m
Line: 3
Column: 18
The expression to the left of the equals sign is not a valid target for an assignment.
the code showing the paths:
LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'
imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
DestDir = imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'
Please what do you do? I am running MATLAB on a Mac system.

line 3: DestDir = imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'
matlab version: 7.10 (r2010a)

Suzzie, why are you assigning a different value to imgDir on two consecutive lines?

I think your code suppose to look like this:
LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'
imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
DestDir ='/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/AlignedFaceImages/'
The cause of an error was the third line. You are not allowed to make (double) assigment like:
DestDir = imgDir = 'string'

Now I get the problem:
1) I agree with Vieniava
2) If the whole code is defined on a single line, then separate each assignments with ;
Ex:
LabelDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/'; imgDir = '/Users/suzzie/Documents/MATLAB/FaceRec/TestDir/FaceImages/'
