Working on the IRAM computers

As soon as you arrive at IRAM Grenoble, an account is created for your project. Project accounts are in general allocated for a period of two weeks and are automatically removed at the end of that period (with no archiving or warning). You should get in contact with your local contact in case you need more time.

At your arrival a computer at the IRAM terminal room is booked for the reduction of your project. Your local contact will provide some information on the computer directories, download the raw data and have a first look with you at the calibration procedure.

Project accounts contain a README file, the `reports`, `calib` and `maps` directories and the `tmp > /scratch/xxxx/` link. In README you will find a description of the account directories and some other helpful information. The `reports` directory contains the calibration results obtained by the pipeline2, sometimes also those from an improved calibration by the astronomer on duty (AoD)3, and AoD's notes to help with the calibration (Sect. ). The data calibration is, by default, performed in the `calib` directory, further data analysis in `maps`.

In order to download the project raw data, the command `getproj` must be executed in the shell prompt. The data are stored in the scratch directory linked by tmp, and are visible from all CLIC sessions launched on the computer where `getproj` was executed.

By default the GILDAS daily version is used. You can execute "`gagiram` mmmyy" (mmm = month, yy = year) to switch to a previous GILDAS release.

At the end of the calibration you may want to save a copy of the project account. Reduced data can either be transferred via `scp` to your home institute or archived on DVDs. From the account home the command ``buildDVD .'' allows you to burn in a DVD all the things there contained. Note that the `IPB` data files are in the scratch of the assigned computer and so by keeping the default distribution they are not saved in the DVD. Finally, it is strongly recommended to check the integrity of the recorded data before the account expires.
