error: subscripted assignment dimension mismatch

Submitted by dominic on Tue, 10/20/2009 - 13:40

Dear REST developers,

When I attempt to run the functional connectivity pipeline in the program with a single subject 4D analyze format image with no mask it returns the message below. What does this message mean? How can I fix it? 

thank you,

Dominic

z-score

Submitted by Pablo on Sat, 10/17/2009 - 18:55

Hi, I have a question regarding how to obtain the Zscore. Particularly I don't know how to calculate the correction for the degrees of freedom (that seems to be a value around 2), since I could not find the actual calculation. Does anyone know how it is calculated?

Also, I would also like to use the Yan's program called y_Corr2p(r,n). But I don't understand what the "n" is. In the comments of the program it says that is the number of pairs, but I don't understand.

thanks a lot, many greetings
Pablo

Error using ==> eq Matrix dimensions must agree.

Dear REST developers,

I'm trialling the REST program using a single subject and specifying a voxel wise ROI. Each time I try to view the ROI as outlined in the manual or run the analysis it produces this error: 

Exception occured.    (MATLAB:dimagree)
    Error using ==> eq
Matrix dimensions must agree.

Error in loading covariables when doing batch FC analysis

Submitted by frog on Wed, 09/30/2009 - 21:29

Hi, REST experts,

I was doing the batch FC analysis. I listed the subjects' covariables (9 variables) in a text file (Covlist.txt) as follows, 
C:\REST-analysis\Cov\Sub_001_detrend_filtered_cov.txt
C:\REST-analysis\Cov\Sub_002_detrend_filtered_cov.txt
C:\REST-analysis\Cov\Sub_003_detrend_filtered_cov.txt
C:\REST-analysis\Cov\Sub_004_detrend_filtered_cov.txt
......
C:\REST-analysis\Cov\Sub_017_detrend_filtered_cov.txt
