How to use ADNI's data ?

Dear Labs ,

We have some questions of download from ADNI's data.

As we knew , FunRaw and T1Raw data file format must the same.

But for the file size is differen that we saw the demo data.

 -the FunRaw data have 240/item and

 -T1Raw have 120/item.

We have confuse that how to use ADNI's data to put in the FunRaw and T1Raw file ?

Thanks and Regards,

Dear Justin,

 

do you mean that there are 240 files per subject for the FunRaw? That's no problem; the file size does not have to be the same for the FunRaw and T1Raw data.

Hi Julia ,

Thanks for your feedback.

And our question is FunRaw and T1Raw data format must the same but for the context can different ?

We saw the demodata FunRaw and T1Raw context is different but can running finished.

And we don't know how to use data from ADNI ? 

Thanks and Regards,

For ADNI data, I suppose you have NIfTI data. Then you should start with FunImg and T1Img.

DPABI->Utilites->Check Data Organization will help you organize your data correctly.

If the data format you got from ADNI is DCM, you can just place the fmri-dcm files in the FunRaw folder, and t1-dcm T1Raw folder.

That's it.

Folder structure should format like this (take subj1 as an example):

FunRaw/subj1/(all the fmri-dcm files of subj1)

T1Raw/subj1/(all the t1-dcm files of subj1)

 

Hi ,

Sorry , may I know more detail for t1-dcm ?

For example, we donwload from ADNI website. And we choose "fMRI". We can get the more *.dcm format files.
And these data is for 
FunRaw folder. How about the T1Raw data ?
Due to we don't get the more data from ADNI.

Thanks and Regards,

MPRAGE represents the T1Image.

You also choose the dcm format to download and place the dcm-files in corresponding subject-folders.

We tried it. But still is fail can't finish all process. (our data get from ADNI)
Do you have any idea where can get the data to test ? 
We can run and finshed all process for demo data.

Please show a snapshot of your data organization.

T1Raw data from MP-RAGE.

And FunRaw from 3-palne_localizer or Axial_PD_T2_FSE. The result is same.

We donwnlaod MRI data from ADNI. And total folds as the below :
3-plane_localizer
Axial_PD_T2_FSE
B1-Calibration_Body
B1-Calibration_PA
MP-RAGE
MR_RAGE_REPEAT
