Hi, I am receiving multiple errors and am hoping someone can assist me in my queries, thank you for your help:
I get an error when using c_null_model_udn_sign to generate null models.
Index in position 2 exceeds array bounds (must not exceed 697).
I get an error when I click "generate" in the Network Construction panel.
(The version of MATLAB is 2020b)
I try it several times, but it always happens, even when I don't click Calculate Graph Matrics and Raw Matrix.
To avoid any conflict between toolboxes, All toolboxes, but GraphVar, are removed.
I attach a picture for showing the details of my setting.
I'm getting very high t-values from the GLM (screenshot attached). I wondered if this is an issue due to my setup (also attached) or potentially something else? I also can also only export the f-values, the t-values do not seem to export when I save the results.
Any advice would be much appreciated!
Dear rfmri community,
I am a new user for the GraphVa s/w. My requirement is to use it as a tool for visualizing the network obtained from connectivity matrix of spinal cord (not brain).
Dear rfMRI community,
I've noticed that some graph theory studies use parametric statistics and others non-parametric. I am not sure how they checked for normality of graph metrics. Is there a way in GraphVar to check the distribution of the graph metrics in order to determine whether to run parametric or non-parametric statistics?
Thanks in advance!
I want to normalize the local CC. In contrast to the global CC and global and local characteristic path length, however, I encounter the following error:
"Normalization error: some metrics derived from random networks result in zero which cannot be used for normalization."
Is there any way I can solve this? When I look into the MATLAB file, the file truly contains several zeros. How is this possible?
Thank you so much!
