Hi,
I have some troubles with the parameterization step. I've imported my data, used the "In-house Topology Fix", checked visually the resulting xxx_fix.mat (see attached) and everything looks ok. Hoever, when I run the next step (parameterization), i have the following message in Matlab:

I have the same message when I tried with the example data.... Thank you for your help

Hi Pauline,

I have come across a similar problem. It has to do with the sprintf() function in thenew version of MATLAB no longer taking sparse matrices as input arguments. I think it can be solved by by chaging theta and phi to full matrices.

Things seems to run OK after this. My current problem is actually in the optimzed parameterization step, where I an not getting the same ADC with the example data as shown in the documentation. It would be great if you could let me know whether you encounter the same issue.

Hope that helps!

Hi Trina,

Thanks for your email. If you can email me (at shenli@iupui.edu) your Matlab version, OS and other relevant setting, we can take a look and hopefully reproduce and fix the difference.

Thanks,

Li

hi,I have the same problem as you,have you sole the problem?I need your help,if it's convenient for you,please email me 616974841@qq.com.
 
thanks,

I figure out a simple solution:

theta_east = full( theta(east) );
disp(sprintf('East Center: %05d (%f, %f) pi',east,theta_east/pi,phi(east)/pi));

It works on Matlab 2013a.

Thanks for sharing the solution. -Li

Good morning,
I have the same problem using Matlab 2010a and Windows 8.
Can you help me please?

I got same problem like Trina's. I got worse ADC after running the excise 3.2. The b01-l-hippo-CALD-smo ADC is 9793.8, far away from 1.31 in the documentation. 

My workstation is running 64bit Ubuntu 16.04, Matlab R2016a, 

Thanks in advance!
