Hi there - when I go to download the compiled version of the dcm2nii software, the MRIcroGL, I get an error message. This has happened on multiple computers. Is there an updated link with a version that is currently working? 

In its place, I downloaded the Github version, but cannot figure out the steps to compile the software. Right now, when I use the dcm2niix command in terminal, I get an error message. 

Can someone either advise on how to download a working compiled version, or give advice on how to compile the Github version?

Thanks!

I know some people have had problems with downloading from NITRC. Have you tried a different Browser? Did you download the version for MacOS, Windows or Linux?

Regardless, you can get the latest compiled version by clicking the "Releases" button on Github

If you still have problems with this, can you tell me what problems you are having when you run dcm2niix from the terminal?

Thanks for your quick response!

Just tried to download MRIcroGL on a different browser - still didn't work. It said (Error 2 - no such file or directory). 

Also sending a screenshot of my terminal and the error I am receiving when I try the command. The left window shows the receipt of the software download - or so I thought. The right window shows the error I receive when I try to use the dcm2nii command.

Looking at the error message it does not look like you placed dcm2niix in your path. To run a terminal command you should place it in a common system path (/usr/local/bin/dcm2niix), append the folder with dcm2niix to your PATH, or explicitly provide the full path to the executable ("/Users/hannahwelch/Downloads/dcm2niix_3-Jan-2018_mac/dcm2niix").  Once you install MRIcroGL, it should also provide a graphical interface for dcm2niix (from the Import menu).

Hi Chris

I run Mac with Catalina and I am unable to download Dcm2nii. I tried to down load several times and every time it just down loads to MRIcroGL and after coming across the above post, I tried to down load from this compile and I am able to get the entire file except DCM2 NII

Can you help please 

Thanks

With Macintosh applications, all components are hidden inside the application package (which is actually just a folder). This is different from Windows and Linux. You can find your copy of dcm2niix in a few ways:

1. You can open the application folder by choosing to "Show Package Contents" in Mac Finder. Just select the application you are interested in inspecting, and choose this command by right or command clicking on the application icon.

2. In MRIcroGL, choose the Import/ConvertDICOMtoNIfTI menu item. A new window appears, and in the text region on the right you will see the full path to your copy of dcm2niix as well as version information:

/Users/chris/Neuro/MRIcroGL/MRIcroGL.app/Contents/Resources/dcm2niix -f "%s_%p" -p n -z n -b n "/home/user/DicomDir"
Chris Rorden's dcm2niiX version v1.0.20200331 (JP2:OpenJPEG) (JP-LS:CharLS) Clang8.1.0 (64-bit MacOS)
Example output filename: '1_MPRAGE.nii'

For my example, I can copy the path to the Finder's Go/GoToFolder menu item:
  /Users/chris/Neuro/MRIcroGL/MRIcroGL.app/Contents/Resources

If you only want dcm2niix, and do not want the graphical interface of MRIcroGL, you can get the terminal-based dcm2niix directly from Github

Run the following terminal command to get the latest version for Linux, Macintosh or Windows:
