Problem in learning an MRF model
Hi everyone,
I have a data set containing 847 data points and 12 variables in a 847 x 12 matrix. I need the graphical representation of my data as MRFs. So, I input the data set matrix (and no more parameters) to the "mrf2FitStruct" function, and I get the error messages shown in the picture below:

What do you think is the problem?
I may add that I just downloaded the toolbox and executed the functions "initPmtk3" and "testPmtk3". After running "testPmtk3" I got an error regarding to the data sets. So, I downloaded the data sets using the function "downloadAllData" and now when I execute it I get the following error:
Checking initialization..........PASSED Checking pmtkSupport packages....PASSED Checking pmtkData................downloading http://pmtkdata.googlecode.com/svn/trunk/crabs/crabs.zip to C:\Users\AmirArsalan\Desktop\pmtk3-master\pmtkdataCopy\crabs.zip FAILED
Thank you
