[Neurodebian-users] keep multiple neurodebian software versions

[marco tettamanti]

Dear neurodebian users,
I have been using Debian for serveral years and I was very happy to discover the 
neurodebian project a few months ago!

Having all the neuro-software I need in the Debian repositories is of course 
very handy, and now that Debian 6.0 has been released, I could finally get the 
latest software updates on my server, simply with an apt-get.

However, there is one aspect I am concerned about, where I cannot figure out any 
such efficient solution as when I used to install each software manually.

Basically, there are softwares (e.g. mricron/dcm2nii or fsl), for which I very 
much want to use the same version to analyze a specific data set, in order to be 
sure to keep all relevant processing parameters constant across the experiment. 
Under some circumstances, this may require having multiple software versions 
installed, in order to benefit from software upgrades for newer experiments but 
still be able to use older versions to analyze, modify or review older experiments.

With manual installs, having multiple software versions was rarely a problem.
But with (neuro)debian, I really don't know how to do this. Putting a package on 
hold does not really solve the problem.

Thank you and all the best,
Marco
