Welcome to Help

Hello,

I am a first-year PhD student at RMIT University in Melbourne.

I would like to run some experiments on the images from IBSR.
However, I am having difficulty viewing these images as they are in .img format.
I have sought for help on the website, readme file and the Internet but have not had any luck. Other people seem to not have this problem I guess.
I hope you can help me out.
I am sorry if the question sounds silly. Thank you.

Sincerely,
Anh

Hi Ahn,

I just uploaded a file "OpeningIBSR.imgFiles.pdf" to describe how the IBSR .img files can be opened.  Lots of people have this problem because they are not ANALYZE files, they are raw binary files.  Please look for it here.

Andy.

I have download IBSR_V2.0, which contains 18 subjects of IBSR_01_ANALYZE.tgz and IBSR_01parc_ANALYZE.tgz to IBSR_18_ANALYZE.tgz and IBSR_18parc_ANALYZE.tgz. Each IBSR_01_ANALYZE.tgz folder contains two subfolders that are images and segmentation. But, I am unable to open the disc image files, and also couldn't find where is the corresponding ground truth images of IBSR dataset. Please also provide the information about IBSR_01parc_ANALYZE.tgz folder. I couldn't find IBSR_01_CMA.tgz file that is explained in the readme file.

Hello,

The "CMA" files like IBSR_01_CMA.tgz are basically useless because they are in a format that is hard to open.  That must be why they were deleted.

The ANALYZE files are an old imaging format.  See [url=https://en.wikipedia.org/wiki/Analyze_(imaging_software)]https://en.wikipedia.org/wiki/Analyze_(imaging_software)[/url].  This has been superseded by the NIfTI format, see https://nifti.nimh.nih.gov/.

There are various applications that can open the ANALYZE format such as MIPAV (https://mipav.cit.nih.gov/).

Or you can convert them into NIfTI using:

nifti_tool -infiles IBSR_01_ana.img -prefix IBSR_01.nii -copy_im

See https://sourceforge.net/projects/niftilib/.
