Using the VM¶
The VM comes with an
~/iraf
directory, containing a defaultlogin.cl
&uparm/
.The
geminiconda
environment is activated automatically on login.Start DS9 (or XImtool) and PyRAF in your VM session:
ds9 & cd iraf pyraf gemini
You may then continue processing data as usual. All the IRAF packages from Gemini’s Astroconda channel are available, along with
emacs
&vi
.You can also use DRAGONS (and other conda packages), but it’s better to run those directly on the host machine wherever possible, since processing data on non-x86 machines is an order of magnitude slower when using the VM and you are more likely to run into resource limitations there. Only the IRAF packages require a VM on MacOS.
You can administer the conda packages in
/home/irafuser/miniconda3
as usual, though conda commands might take some minutes to run on the VM. The operating system (CentOS 7) installation is not intended to be user-maintainable.It should be possible to leave the VM running while your laptop is suspended and resume processing later – but you may find that the clock time is wrong on the VM afterwards. There is currently no way to suspend the VM itself.
