Isis tutorial installing

Getting ISIS

Installing ISIS and all the modules it depends on, is not a trivial task.

We therefore provide a complete isis environment that is pre-installed in a so-called singularity environment. Singularity runs very well under Linux and can also be installed under windows, although this is a bit more complex, which is why we also offer an alternative. Note that you will need about 4 GB of disk space for the installation.

If you do not have enough disk space available or if you are not happy/comfortable with installing software on your computer, we also have an option to run the tutorials on machines at the observatory.

Setup for Linux

• Install singularity. How you do this depends on the flavor of Linux that you have installed. On ubuntu systems, this is as easy as executing

sudo apt-get install singularity-container

On other Linux versions different commands are required.

• Create a working directory for the lecture and download the singularity image for isis and the other tools required for the tutorial from https://www.sternwarte.uni-erlangen.de/isis/isis-singularity.img , e.g.,

mkdir xray
cd xray
wget https://www.sternwarte.uni-erlangen.de/isis/isis-singularity.img

• you can then launch the singularity environment as follows:

cd xray
singularity run isis-singularity.img

This brings you into an environment that contains most of the relevant X-ray astronomical software, such as, e.g., fv (which you might want to use to display X-ray astronomical data files). You then launch isis by typing isis:

 isis

Setup for Windows

• Install singularity using the instructions on the singularity homepage. This is a somewhat involved process, but doable in principle if you are ok with computers. If the instructions don't

• Follow the instructions above.

(an alternative is currently being prepared - watch this place)

Working on Remeis observatory computers

• If you do not have enough disk space on your computer or do not want to install things locally, contact Ingo Kreykenbohm at the email address given out in the lecture and ask him to create an account on the Remeis computers for you.

• To work on the computers from home, once you have the Remeis account, install the X2go remote desktop environment, following the instructions here.
