Hi everybody! I am using geometric morphometrics in a study on mandibles of mice. I have encountered problems using programs in the IMP series, and I would be very grateful if somebody more experienced with these could give me a hint on what to do here:
1)I load an output file from CoordGen and a GroupList file into CVAGen. The program displays the landmarks but does not finish the analysis, instead posting an error message: The within-group sum of squares and cross products matrix is singular. I have inspected both input files several times; I cannot find any error; they do also perform well in PCAGen. What does the message tell me about my data? 2) I load two X1Y1CS format files into TwoGroup. The landmarks are displayed and I can calculate Goodalls F. Anyway, when I click on F test, Procrustes I am getting an error message saying that matrix dimensions must agree. Why is this? What do I have to change? If anyone wishes to reply to me directly, my email address is: [EMAIL PROTECTED] Thank you very much and let me know if I can return you a favor.
