Triple axis spectrometer data is stored in ASCII files. These ASCII
|
|
files are formatted in a format compatible to the ILL's triple axis
|
|
data file format. Data files can be found in directories:
|
|
<pre>
|
|
|
|
/home/INST/data/YYYY/HHH
|
|
|
|
</pre>
|
|
on the instrument computer or in
|
|
<pre>
|
|
|
|
/afs/psi.ch/project/sinqdata/YYYY/INST/HHH
|
|
|
|
</pre>
|
|
on any other LNS unix system. INST is a placeholder for the instrument
|
|
name in capitals, YYYY for the year of data collection. HHH is the thousands
|
|
directoy. In order to facilitate file handling, data files are grouped into directories
|
|
containing thousand data files each. Thus files 0-999 will be in the 000 directory, files
|
|
1000-1999 in the 001 directory etc. Data files are
|
|
named according to the SINQ naming convention:
|
|
<pre>
|
|
instYYYYnTRRRRR.dat
|
|
</pre>
|
|
with inst being the placeholder for the instrument name in lowercase,
|
|
RRRRRR the run number as a six digit number and YYYY again the year of
|
|
data collection. Example: tasp2002n000330.dat is data collected in run
|
|
number 330 in 2002.
|
|
</p>
|
|
<p>
|
|
The last measured data file can be discarded by typing the command:
|
|
<pre>
|
|
|
|
<em>killfile</em>
|
|
|
|
</pre>
|
|
in SICS. SICS managers privilege is required for this command.
|
|
</p>
|
|
<p>
|
|
Automatically generated log files can be found in the /home/INST/log
|
|
directory for each day. They are named according to the scheme:
|
|
<pre>
|
|
|
|
autoYYYY-MM-DD@HH-MM-SS.log
|
|
|
|
</pre>
|
|
YYYY is again the year, MM the month, DD the day, HH the hour, MM the
|
|
minute and SS the second of file creation.
