Write data set name to LINE (card image 2) in SEG-Y 3200 byte ASCII/EBCDIC header. Miscellaneous other small fixes to SEG-Y output.

Modified OYO-8 format to properly import File Number, Low Pass Filter, number of vertical stacks, gain, time and date. Also import field notes, geophone y-locations and elevations.

Made sure that modified Oyo imports are written to SEG-Y files.

Version 3.07 16 December 2004

Fixed problems with trace display regarding clip and width. Also with autoscaling in this regard to trace number. This also concerned gain to global max.

Fixed minor problem with rubber band box appearing on an expose or resize message.

Changed some of the dialog entries where floating point numbers reverted to exponential format.

ASCII import now tries to estimate number of traces and samples.

Changed so date is transferred from SEG-Y to SEG-2.

Version 3.05 27 August 2004

Fixed naming convention so that SEG-Y files with multiple records carry the record number at the end of the name, as FILENAME-SEQ#. SEQ# is preceded with 0's if shorter than max digits in file.

Changed output format for source and receiver location to F10.1

Version 3.04 27 May 2004

Fixed bug where locations were scaled by 100 in SEG-Y output but scale factor was written as -100. On input, scale factor was ignored as it was less than 0.
Version 3.03 5 May 2004

Added a menu option to concatenate records in a SEG-Y file. This is used when the number of traces per record is not correctly specified (e.g. specified as 1) and the file contains only a single record.

Version 3.01 1 March 2004

Added truncation and resampling of traces. Truncation leaves sample rate the same but loses values on the end of the traces. Resampling keeps same trace length in time, but with the new number of samples, changing the sample interval accordingly.

Added NMO correction. This displays a line based on a flat reflector and allows the user to modify the line numerically or graphically to fit a curved event. Results show velocity and depth of reflector.

Fixed problem where plotting colors would change after palette change in F-K filter screen. Traces used to change color from blue to green, for instance.

Version 3.02 23 April 2004

Fixed loss of INI file. Now, INI file is read and INW file is created with registration information. If program crashes, old INI file is intact. If program successfully completes, new info is added to INW file, old INI file is deleted and INW file is renamed to INI.

Added odometer to Combine menu option showing which file is being read and combined to output file. Also fixed so SEG-Y read retains the field in bytes 9-12 of the trace header and, if this is zero when the shot is combined to the SEG-Y output, this is set to the number of the record in the file.


Version 3.00

Changed ini file directory to execution file directory.

Fixed so that with SEG-Y, if number of traces per shot is 0, user is prompted.

Prompts user for which shot to read in multiple-shot SEG-Y. Shots counted by file size using number of shots per record times number of traces times number of samples and format.

In file conversion to SEG-2 or SEG-Y, SEG-Y files with multiple shots are exported with the shot sequence number (1, 2, 3...) appended to the export file name.

Changed toolbar buttons so all have transparent background.

Added feature to combine multiple files into a single SEG-Y file. All files must have same size data, same sample rate, same trace length, same number of traces per file.

Added bandpass filtering with interactive windows.

Added F-K velocity filtering with interactive windows.

Added import/export of flat ASCII or CSV files.

Fixed bug in FIRSTPIX format import.

Version 2.08 18 February 2003

Fixed bug in radio buttons on user defined import dialog

Version 2.07 22 August 2002

Fixed bug where output of sample rate in SEG-2 format rounded up to nearest hundredth of ms (nearest 10 usec).

Fixed bug when file names have no extension and therefore no dot (".").

Version 2.06 5 August 2002:

Added Integration, Differentiation, DC Level Removal and DeTrending

Fixed bug with autoscaling when only one trace is present.

Fixed bug with autoscaling for horizontal traces where vertical labels were miniscule.
Now no more than 12 major divisions are allowed when plotting by trace number.

Version 2.05 25 July 2002:

Wavelet selection now works when horizontal display is distance.

Added 1-D flat refraction interpretation using slope/intercept time

Version 2.02 February 2002:

Various minor bug fixes

Version 2.01 18 January 2002:

Fixed it so it will read SEG-2 files in cases where the file and trace header string fields contain imbedded nulls and other non-printable characters.

Version 2.00 10 January 2002:

Help is now available.

A toolbar has been added

File Merge has been added to merge several input files to several output files. This can be used, for instance, to convert from shot gathers to common offset gathers or to take down hole multi-component data and sort it into separate files each containing a single component.

A new data format, the Oyo Suspension Pslog format has been added. This format is designed mainly for use with File/Merge as the data contain 2 pairs of 3 components.

This What's New file has been started.
