Utilities Manual

These programs are run from a MS-DOS or UNIX command prompt. They are not run using a mouse and pretty windows ! They also can make use of a number of different file formats. Thus, they are portable to many different computer systems.

7.1 AUTOCOR Auto correlation utility

The Auto correlation function finds periodicities in time series data. When applied to epr data, the function returns splitting constant values without respect to nuclear spin.

Usage:

• autocor [-a #.#] [-f#] filename
• -a #.# Max hyperfine (G) for searching, default= 20.0
• -f# filetype:

Example: autocor -a 10.0 -f0 test.lmb
This would autocorrelate the NIEHS binary format file test.lmb for hyperfine couplings up to 10 G.

7.2 - FREP - File Reporting utility

Prints out header information from EPR data files.

Usage: frep [-e] [-n] [-s text] [-p psfile] [-f#] filename

Automation example

You can use the command prompt shell to automate the process. For instance, If you have several files with the ".lmb" suffix, you can use the following command to search for "nitro" ( UNIX users try 'foreach' ) :

for %1 in (*.lmb) do frep -s nitro %1 >> output.txt

All the files with the suffix ".lmb" will be searched for the text "nitro" and, if successful, the information text lines will be redirected into the file "output.txt" which can be examined or printed.

Printing example

Using the "-p" option will instruct frep to produce postscript output suitable for any postscript viewer or printer. This command creates a postscript file "test.ps":

frep -p 080295-1.lmb > test.ps

To resize the data to the page and output the data directly to a postscript printer:

frep -p 080295-1.lmb > test.ps

7.3 - FCON - File Conversion utility

Usage: fcon filename1 filetype1 filename2 filetype2

Filetypes:

Example: fcon test.spc 3 test.lmb 0

This would convert the file test.spc from Bruker format to a new file test.lmb in the NIEHS binary format.
