1. To run the atsTools on the sample data in this directory, copy the files obtained
   from the ATS 600 logging session into the atsTools directory (i.e. one level up).
   The files obtained from the ATS 600 are:
       ATS_200412132237.cap
       ZDA_200412132237.cap

2. Now go to up to the atsTools directory. 
3. Rename ATS_200412132237.cap to ATS_200412132237.atspc.
4. From a DOS prompt run the command 
     parse_atszda.exe ZDA_200412132237.cap
   and a file 
       ZDA_200412132237.zdapc 
   will be generated. 
5. Create an options file. Instructions for creating an options file are given
   in "README ATS trajectory.txt". You can also use the provided sample options 
   file in the sampledata directory for this set of data. 
       13Dec04_zeroheight.opt
   Copy this file into the atsTools directory. 
6. Run the command ATS_traj from the Matlab prompt. 
7. Select the appropriate files that the dialog boxes ask for. The dialog boxes
   ask for one .opt file, one .atspc file and one .zdapc file. 
8. The scripts should run and generate five text files:
       ATStraj_llh_rad.txt
       ATStraj_LLHvel.txt
       ATStraj_NEDvel.txt
       ATStraj_XYZ.txt
       ATStraj_XYZvel.txt
9. The ATStraj_XYZ.txt contains the information to be used as a reference
   trajectory to be used in rkwin. Note that the data in seconds has to be
   converted to milliseconds before rkwin will accept it. This is done 
   automatically when rkwin is called from within gieTools.
