Intensity normalization in T1 when using VBM module

Hello to everyone.
 
I used the VBM module employing DARTEL segmentation in order to segment and spatially normalize a sample of T1 sequences.
Now I would like to perform further analysis using the files swco_ obtained from the segmentation, i.e. the entire brains spatially normalized (please advise me if I'm misinterpreting this kind of file).
 
The question is, was some kind of intensity adjustment applied to the original T1 during the preprocessing steps?

Unespected error in DPARFSA

Hello to everyone.
 
I'm trying to use DPABI to preprocess some structural and resting state data.
I would need to spatially normalize both structural and functional to a template made on this specific sample of subjects, in order to later perform some unsupervised clasification.
 
However, I get the error in the screenshot attached.
I also attach the screen of the settings I used which generate the error.
 
How could I solve the problem?
 
Thanks a lot.

Problem with automask

Hi there

I have some problems with the normalisation step. First of all, do I need to run automask if I want to use normalize by using EPI tamplates? What is the best normalisation step? EPI or T1?

If I run automask I get the following error (see attached file).

If I run normalisation without automask, I get an error saying that the automaks does not exist, so I assume I need automask to run the normalization?

Any help is very much appreciated.

Thanks a lot in advance

error in DPARSFA - Reference to non-existent field ROIDefForEachSubject

Dear experts,

I tried to preprocess my resting state data with DPARSFA version 4.3_170105 in MATLAB 2015a. I get the following error: "error using DPARSFA_run>(parfor body) (line 4088) Reference to non-existent field 'ROIDefForEachSubject'.

Attached is the screenshot. I searched the forums, and I saw the suggestion that this might happen if you don't click the Define ROI button. However, I did click the button and defined the ROIs, by navgating to them in the window that popped up, and made sure the paths to mask files were correct.

T1 Average image tools

Hi,

Trying to average multiple anatomical data for one subject using T1 Average image tools, I got this error. I think its the way how im arranging my data. Can you please let me know how I can arrange it correctly.

Error using cd
Cannot CD to C:\Users\lab1\Documents\96\T1Img_MultiRun\C:\Users\Meaneylab1\Documents\96\T1Img_MultiRun (Directory access failure).

RatFCMAP space issue

Hi there,

I've noticed that when running rat functional connnectivity analysis that the resulting FC image does not exist in the same space as the original images.

In the image below it can be seen that the Schwarz atlas (top left) and pre-processed resting-state image (right) are coregistered. However the FCMAP generated appears to be much larger, with many voxels outside of the brain. Why has this occurred?

Thanks
