MulabDataLog

< The internal structure of mulab: Model functions | Index | How to install mulab >

Before you start using Mulab you must choose your path policy.

You will be storing your data into some place and your fit logs may go some place else.

Fit log files can be reloaded to reproduce identically the fit on the same data
or as a starting point for a new data set.
Their name contains the model components, the run number, the detector groups, and a version number

Now please read carefully, choosing among the following situations the one that fits you best.

On a linux personal pc

Launch matlab (hence mulab) from the following path

   /home/user/mulab/facility/instrument, e.g. /home/derenzi/mulab/psi/gps

which must contain the proper MULAB.mat (if not generate one). This path name is stored in the global variable

   MU_PATH.ROOTDIR

Select the following from the SAVE/QUIT dropdown menu:

Store data in the following data path name, to have a single data version for all pc users

   /home/musr/facility/run/instrument/sample, e.g. /home/musr/psi/run_05_07/gps/YBCO

or else, for private use, in

   /home/user/musr/facility/run/instrument/sample, e.g. /home/derenzi/musr/psi/run_05_07/gps/YBCO

This path name is stored in the global variable

   MU_PATH.DATA

when you select it with the PATH button.

Mulab will store logs in the following log path name

   /home/user/mulab/facility/run/instrument/sample, e.g.  /home/derenzi/mulab/psi/run_05_07/gps/YBCO

This path name is stored automatically in the global variable

   MU_PATH.LOG

thanks to the home+Mirror settings

Automatic refresh:
When a new sample is analysed, the user must change data dir (PATH button on the MULAB GUI interface)
and the log is adjusted accordingly.

If you choose

you will be asked for a new log path each time you change data path

On a linux PSI llc box

Select the following from the SAVE/QUIT dropdown menu:

In this case set the data dir to, e.g.

  /afs/psi.ch/project/bulkmusr/data/gps/

and the log will be forced (excuse the improper word 'Selectable') to\\

  /afs/psi.ch/user/x/xuser/mulab/live/

Alternatively, choose

then link data to e.g. /afs/psi.ch/user/x/xuser/data/gps/sample
e.g. by moving into that directory and issuing the following command

   xx=268 ; while [ $xx -lt 290 ] ;
   do ln -sf /afs/psi.ch/project/bulkmusr/data/gps/deltat_pta_gps_0${xx}.bin ./gps00${xx}.bin;
   xx=$((xx+1)); done

Logs will be mirrored into /afs/psi.ch/user/x/xuser/data/gps/sample/log

On a WIN personal computer (tried under XP, Vista and Windows 7)

Launch the program from

  C:\Documents and Settings\derenzi\mulab\psi\gps

(strongly suggest to have facility and instrument specific paths, since MULAB.mat is specific)

Select the data path with the PATH button; the log path choice is offered immediately after

If you choose

it assumes that the data are in C:\....\MuSR\subdir\subdir1\...
and it mirrors automatically the logs onto C:\....\Mulab\subdir\subdir1\...

Top

On the ISIS cabin WIN PC e.g. musr (tried only under XP)

Launch the program from

  C:\Documents and Settings\musr\mulab\musr

(strongly suggest to hava instrument specific paths, since MULAB.mat is specific)

In all cases select data path to \\musr\data. Logs will be written in C:\Documents and Settings\musr\mulab\musr\log
You can move and rename this directory when you change sample if you wish to keep each sample results separate.
