Dear export,[/b]

i am very happy to write to you.[/b] [/b]I am a new conn learner, and also a green hand of FMRI data analysis.[/b] [/b]After i read the menu , i got puzzled several times,[/b] [/b]there exist errors and warn[/b]in[/b]gs much time.[/b] [/b]Because i have no structural images, so i do not know which choices and blanks or values i should leave it as default.[/b] .[/b]Can you give me some suggestions?[/b]

And this time i tried,[/b] [/b]and made a little success that i finish the first 3 steps by the men[/b]u[/b] , mine is conn V1.0.This error is coming from the illustration of the 4th step as follows,[/b]

spm
Initialising parameters : ...done
Output images : ...initialised
Plane 46/46 , block 1/1 : ...done
Spatial non-sphericity (over scans) : ...writing resels/voxel image??? NaN's cannot be converted to logicals.

Error in> spm est_smoothness at 260
FWHM(~FWHM) = 1;

Error in> spm_spm at 909
[FWHM,VRpv,R] = spm_est_smoothness(VResI,VM,[nScan erdf]);

Error in > conn_process at 1431

Error in> conn_process at 19

 Error while evaluating figure WindowButtonUpFcn

and the other is :

Error in > conn_menumanager at 112

the last one is :[/b]

In an assignment A(I) = B, the number of elements in B and
I must be the same.

Error in > conn at 1554
t1(CONN_h.menus.m_results.y.idx)=S1;
 Error while evaluating uicontrol Callback

that is all.[/b]

By the way ,the examples are 2 groups comparison, but i tried 3 grups i want to compare each 2 of them,and i tried the way selected the 2 i wanted, but none of the time successed.so i do not know why? and i only have one condition.[/b]

Are there any difference between fixed effects and random effects?[/b]

Thank you very much for reading the mail.Waiting for your reply.[/b]

i really find headache and every time repeat errors but can not reach the successful bank , really sad and need guidence. Thanks again.Best wishes .[/b]

Yours sincerely,[/b]
