1. Utility Programs and Scripts
Instillation
File conversions
Plotting
Analysis tools

2. Utility packages in gamit/globk
The utilities are located to three places:
~/gg/com shell scripts
~/gg/kf/utils programs
~/gg/gamit/utils programs
Use ‘ls’ on above to list, ‘grep #doc *’ in /com to get one-line description of scripts
Nearly all of the utilities and shell scripts are self documenting

4. Data archiving scripts
sh_archive_soln - Saves main files from gamit day directory in archive structure
sh_casefold - changes the case of file names either to upper (u) or to lower (d)
sh_cleanup - Cleans up day directories by compression and deletion
sh_crx2rnx - converts Hatinaka compressed files to rinex
sh_rnx2cxr - converts rinex to Hatinaks compressed
sh_dos2unix - Converts dos text files to Unix

5. Plot generation
sh_enf_to_vel - converts ensum and enfit summary files to standard globk velocity file format. Allows plotting of globk direct velocity estimates with time series velocity estimates
sh_gamit_atmos - plots the atmospheric delays from gamit solutions
sh_gamit_baseline - plots baseline from gamit solutions rather than globk solutions

6. Plot generation (continued)
sh_glist_gmt - Allows plotting of distribution of stations in times
sh_globk_scatter - plots baseline scatter as function of baseline length
sh_histogram - plots histogram of position residuals
sh_plot_profile - used in conjunction with program profile to plot velocities projected on to a profile.

7. Plot generation (continued)
sh_plotcrd - plots coordinates as a function of time
sh_plotvel - draws velocity arrows on a map
sh_baseline - shows relative postion vectors as a function of time

8. File transfer scripts
sh_get_hfiles - gets ascii hfiles from SOPAC (usually igs1, igs2, igs3 the three global networks)
sh_get_nav - gets navigation files (*.YYn files) from archives
sh_get_orbits - gets orbits either sp3 or gamit g-files (SOPAC only)
sh_get_raw - Gets raw data for selected sites from SOPAC
sh_get_rinex - Gets rinex data from cddis, sopac or unavco
sh_get_stinfo - Gets updated station.info from sopac for the global network

9. Conversion
sh_glbtosnx - shell to convert binary hfiles to sinex (uses glbtosnx)
sh_l_to_xyz - converts gamit l-lfile to XYZ files
sh_svdiff - Differential positioning using pseudoranges
sh_svpos - Point positioning using pseudoranges

10. Globk utilities ~/gg/kf/utils
These are all programs (directory contains source code)
These programs are self documenting

11. Conversion programs
apr_to_vel - converts a globk apr file to velocity format (sigmas are zero)
doy - doy converts dates to various formats:
***TODAY*** IS:
Date 2002/01/31 20:38 hrs, DOY 31 JD MJD
GPS Week Day of week 4, GPS Seconds Day of Week Thu
Decimal Year
gapr_to_l - converts globk apriori file to gamit lfile format
unify_apr - Allows removal of extra stations, changes of positions and velocities in globk apriori files.

12. Binary h-files and gfiles
swaph -- switches big-endian to little-endian and visa-versa (needed to use SGI binary hfiles on Linux systems)
glbtog -- creates gamit g-files from globk solution with orbits
glbtosnx – creates a SINEX file from a globk binary h-file; run with ‘-h’ option to get a ascii version of the h-file header

13. Velocity field manipulation
genrelref - Takes standard velocity field file and generates one as difference from site in list
(similar to getrel except does not require org file with BRAT on. Uses velocity files themselves.
Sigmas may be overestimated.
velcom - Allows comparison of many velocities files.
produces average values and RMS of values
velrot - Allows velocity fields in different frames to be compared

14. Summary Utilities do lots of different tasks
Often you can use them as template to make your own scripts
