Log File

During acquisition, when runs are started and stoppped entries are made in the file lamps.log (in the directory from where lamps is started). The data written has the following fixed information fields:
Run Name
Setup File
Start Date
Start Time		 Stop
Elapsed Sec
Bufs Acq
Bufs Proc		 Events
Evt/s
Dead Time
List Bytes		 Scaler 1
Scaler 2
Scaler 3
Scaler 4		 Remarks

(Only 4 scaler values are stored in lamps.log, if you have more scalers you will find them in scaler.log)

In addition lamps.log can store 12 additional optional data fields. The names of the fields themselves can be changed. By default (when LAMPS is started with no lamps.log file) the fields are:

Ion, q+
E, TV
NMR, I
CI (scale)		 Target
Tgt. Rot.
Info 1
Info 2		 Info 3
Info 4
Info 5
Info 6
These fields (as also the Remarks column) are to be filled by the user. The fields can be filled at any time during or after the run. See View, Edit (below).

                 View, Edit

When View, Edit is selected a new window opens:
  1. To change any of the optional headings, click the heading.
  2. The data of the ongoing run or the last run will be displayed. For an ongoing run, the second, third and fourth columns will show "No information"
  3. To view the data of another run use the Prev, Next, Home and End buttons.
  4. Click Delete Entry to remove the log file entry which is currently displayed.
  5. Click Delete All to remove all log file entries.
  6. The data for the fixed inforation fields (except) Remarks are inserted by LAMPS and cannot be altered
  7. The data for the optional fields must by input the user. Click in the relevant area and insert the information

                 Make Word File

 This can be done at the end of the experiment, or offline on another computer where the lamps.log file has been copied. A MS-Word file caled lampslog.rtf will be created in the working directory. If you copy this file to a Windows partition or to a Windows PC, it can be opened in MS-Word. You can also open it directly in Linux with OpenOffice.org, but in this case you will need to drag the column separators of the table (to adjust the column widths) as shown below.

A printout of the word file is very useful while working on the analysis. You could even export the columns to an Excel worksheet.

The log file itself (lamps.log) is a text file with all the information in readable form but lampslog.rtf is better formatted for printing, creating additional columns etc.
