Version 1.14 26 April 2010

Added "faults" (horizontal refractor velocity discontinuities) to GRM interpretation so velocity
analysis curves are split into segments at each "fault". Faults can be added in the GRM results
windows, the shot pair analysis window and the X-Y analysis window.

Extensive revision of help file and manual to reflect new features, correct minor errors and
omissions and to more fully document the GRM interpretation features.

Added functionality to read and decode first break information from SIP and SIPWin *.PIK files
if a file with the same name as the SEG-2 file but with the PIK extension is found in the same
directory and the breaks are not stored in the SEG-2 file.

Fixed problem with radio buttons in Depth Section dialog.

Fixed problem with offline data not being saved after being edited in shot header. Note that
offline data are not currently used.

Added odometer display to velocity display in GRM interpretation Also upgraded several other
odometers so cursor position and other pertinent information is displayed on the status bar.

Added first break index to bytes 233-236 of trace header in SEG-Y format.

Fixed SEG-Y import and export to set last 4 bytes of trace headers to "BRAK" if first break data are in 233-236 and to test for that. Picked flag is set to FALSE if no picks are detected.

Fixed problem with program crashing when using Survey Planning/Create Model.

Fixed problem with crashing and/or retaining last model found in flat layer refraction interpretation in cases where suitable break point(s) not found.

Fixed problem with velocity analysis curves having too small an allocated range when geophone spacing was smaller than average.

Fixed problem with program crashing if Calculate/Invert Model was used after canceling out of Estimate Model.

Calculate/Invert model now just does one iteration per use.

Added more functionality to odometers that show the mouse position as the mouse is moved around inside the graphs.

In edit 2-D model mode, using the right mouse button now drags the entire layer, while left button drags a single vertex.

When dragging a vertex or layer in 2-D model display mode, the model is checked upon release and illegal models with overlapping polygons are disallowed. Model is backed up towards the original model until it is legal.

Added ability to change user name using Help/Register.

Using Help in the Assign Arrivals mode takes you to the help for Assign Arrivals.

Description of Assign arrivals regarding use of left/right mouse buttons to move layer transitions is improved in the manual and help files.

Added a menu for survey design. Create survey creates a spread from user input, gets model velocities and depths from user and creates synthetic data. Create Model creates a model using existing geometry.

Added a Transfer Synthetic to Data to the File menu. This copies the synthetics to the data for testing, adding noise if desired.

Fixed problem with travel time label being set to Velocity when View/Properties was used in GRM window.

Version 1.09 September 2007

Fixed minor problems with display of shots in GRM interpretation

Version 1.08 21 August 2007

Fixed problem with Edit Shot Headers which appeared when some traces were dead.

Fixed import so all traces get picked to at least the first sample (so there are no dead traces by default).
