Hi,

I am trying to use DTIPrep on an Ubuntu 22.04 machine.

I downloaded the DTIPrep-1.2.11.tar.gz file corresponding to the DTIPrep1.2.11_linux64 release from: 
https://www.nitrc.org/frs/?group_id=283

After decompressing the file to a folder on my choice, when calling the DTIPrep executable in the bin folder, the process exits without launching the software with the following error:
$ ./DTIPrep
./DTIPrep: error while loading shared libraries: libQtXml.so.4: cannot open shared object file: No such file or directory

The library is not found in the lib folder. Am I missing some step? If not, can the library be bundled with the compressed file and the issue be fixed, please?

Thanks for your work

The library issue can be resolved by installing the library, pls contact with your system administrator. 

If it's your own machine under your control, that error came from QT XML library. You can try after installing the library, DTIPrep doesn't automatically build or install QT libraries.

You can refer to below site for your reference.

Hi,

> https://ubuntuhandbook.org/index.php/202...

Had tried following the instructions this morning to no avail; have just retried, probably more carefully, and fixed the problem. For the records, after adding the package archive for Ubuntu 22.04, it sufficed to install qt4-default.

Thanks for the support SK.
