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.

with the VS extension is found in the same directory and the breaks are not
stored in the SEG-2 file.
Added .SEG to the list of searched-for file extensions when importing (SEG-Y)
Added functionality in trace display and shot header editor to flip trace
Added force to SEG-Y read when trace file extension is SGY.
Fixed problem with simple and Hatherly pick when trace values were small
(max less than 1).

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.

with minor or no edits.
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

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
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.

Added a feature to handle a geophone string geometry that
is not monotonically increasing or decreasing, where geophones are placed
out of order.

saved in cases where a GRM interpretation was attempted but failed because
no overlapping segments were found.

appear on shot window instead of main window.
Added capability to import east and north coordinates
along with elevation coordinates

pressing esc to delete segment would work.

or slope/intercept velocities existed.
Fixed minor problems with display of shots in GRM
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).
