Dear SPM users
I am using Biological Parametric Mapping (BPM) toolbox v1.5 in SPM12 for running voxelwise correlation analysis between two groups. I am following the WFU_BPM guide (https://www.nitrc.org/projects/wfu_bpm/, step-by-step correlation - p.12) for setting up the design and selecting Homologous Correlation Field when asked for the type of the analysis.
When I try to display the results through the SPM GUI, I get the following error message:
-------------------------------------------------------------------------------------------
Output argument "u" (and maybe others) not assigned during call to "spm_u".
Error in spm_uc_RF (line 30)
u = spm_u((a/max(R))^(1/n),df,STAT);
Error in spm_uc (line 31)
u = spm_uc_RF(a,df,STAT,R,n);
Error in spm_getSPM (line 709)
u = spm_uc(u,df,STAT,R,n,S);
Error in spm_results_ui (line 261)
[SPM,xSPM] = spm_getSPM;
Error while evaluating UIControl Callback.
---------------------------------------------------------------------------------------------
In the SPM scrips, I found functions calculating 'T', 'F' and other statistics, however, selecting Homologous Correlation Field results in 'C' statistics (for correlations) in the SPM.xCon.STAT struct.
Has anyone of you faced the same issue before? Any input is highly appreciated!
Best regards,
Plamina Dimanova
