SD.M

MATLAB toolbox for processing of SDF (StelarDataFile) files. The whole toolbox consists of a single m file (SD.M), so to use it, simply copy sd.m to your current working directory. No other variables will polute your workspace.

Usage

Initialization

To initialize some local variables, start with sd ini or sd('ini'). At that that point, two global variables are created:

• SDF holds all mesurement data, as read from .sdf file

• SDP holds all settings parameters, necessary to run SD toolbox

Command list

 SD INI                       - initialize SD session
 SD OPEN {filename.sdf}       - open SDF file
 SD OPEN +                    - next file will be appended
 SD REOPEN                    - open last file again

 SD ZONE {i}                  - show T1 fit for zone i
 SD RECALC                    - RECALCulate all zones

 SD SHOW
 
 SD DIPS
 SD('DIPS',0, {'R','I','A'})  - 0 means all blocks,
 SD('DIPS',1:3, 'A')          - blocks 1:3, 'A'bsolute

Parameters

Use these paramters to modify SD.M behavior:

SD.IP                         - Initial Point for FID integration
SD.EP                         - End Point for FID integration (EP=0 means all)
SD.IB                         - Initial BLOCK for FID integration
SD.EB                         - End BLOCK for FID integration (EB=0 means all)
SD.ZONEFIT = {0|1}            - do fit with zone plots or not
SD.FIT2C   = {0|1}            - let ....
