Hi, I have some questions about the results from an NBS analysis on raw connectivity matrices. For questions, we could look to the example NBS table in the manual (attached).

1. Could you expland on exactly how (i.e., equation or formula) the alpha value in the 5th column is calculated? I'm having trouble figuring this out from the NBS papers. e.g., is the alpha derivable from the other columns in the network inspector table?  

I was wondering if someone could help with an issue I've encountered in pre-processing. I have successfully gotten through normalizing my subject files to CSF, white matter, and grey matter. However, after it completes this, I get the following error message: 

Hi,

I wanted to run the normalize step and get an error saying that file2mat function is missing. Does anyone have an idea, what to do?

Thanks

Hello,

I am just starting per-processing data from a resting session (7min) and a task session (20min) using dpabi.

I was wondering if the 2 sessions (rest and task) should be pre-processed together or separately.

Any advice on this isssue would be greatly appreciated.

Thank you in advance,

Ekaterina

Hi dpabi developers,

I got an error while doing multiple comparison correction for a Correlation Analysis in dpabi. First, I tried to compute AlphaSim Correction, but in the results report it is suggested to set a Cluster size of above 2000 voxels, and it seens weird to me, since I have never got a report like this. Afterwards, I tried with GRF and FDR Correction, but it appears an error every time I try to do it.

This is the error (first, I tried to do GRF, and then FDR Correction):

Dear Chao-Gan,

I used scrubbing method to reduce the effects of head motion following reviewer's suggestion, but I have some questions about it, as follows:

1. Does this method directly delete 'bad' time points?

2. Is there any file containing the information about the remaining time points for each subjects after scrubbing? I would like to easily check which subject to be excluded.

Hi dpabi team!

first of all, thaks for developing such a useful tool as dpabi and for maintaining it as an open source software.
