[Mristudio-users] Change Data Format-JHU_pediatric_24_SS_159parcellation_atlas

Wed Apr 1 23:31:41 EDT 2015

Dear Dr. Mori and Dr. Xin,

I have converted JHU_pediatric_24_SS_159parcellation atlas to .hdr/.img format. I am using it for the connectivity analysis. I didn't get any error, but some ROIs are not defined. I attached two files. Could you please look at them and tell me how can I solve that problem? Do you have more information about each RIOs like coordinates?

Any help will be appreciated.

Thanks,
Elveda

Dear Dr. Mori,

I got the matrix size right 160x192x160/1x1x1 and I got the data format .hdr/.img format.Now I am using it for my connectivity analysis. I appreciate it.

Thanks,
Elveda

The matrix is 160x192x160 / 1x1x1 mm.

The easiest way is to load one of the atlas images, for example the b0 image as analyze, which loads the image with correct matrix and voxel resolution information automatically. Then you can load the ROI file as ROI (loaded automatically with correct matrix size) or as an image (as a raw file). As a raw file, you need to specify the correct matrix size but because another image (in this example, the b0) is already loaded, you can use the default parameters.

Dear Dr. Xin,

Thank you very much for the response. I tried it in both DtiStudio and RoiEditor, but I couldn't get the matrix size right. I really need that atlas for my connectivity analysis. You created JHU_neonate_SS_122parcellation atlas .hdr/.img format and I can use it with any problem. Could you please help me to get JHU_pediatric24_SS_159parcellation in the same format.

Thanks,
Elveda

You can load the .dat file as a raw word image file into any mristudio software (DtiStudio, DiffeoMap or RoiEditor). Then you can save it in analyze format by using the "save image" function.

Dear DTI Studio Users,

I am trying to use  JHU_pediatric24_SS_159parcellation atlas for my connectivity analysis. The data format is .dat/roihdr. I need to have this data .hdr/img format. I cannot use it now. I couldn't find how to convert it to .hdr/img format. Could you please help me how to do that? I will be really appreciated.

Thanks,
Elveda
