New QSEIS application
QSEIS is a powerful application that replaces the sli and setdiscfold utilities. It displays key file header values, such as sample rate, fold, and sort-keys, like its predecessor sli. However, it offers additional features, including a tabbed display showing the processing history, support-files table, character and binary reel headers, trace header ranges, and the option to list selected trace headers over a user-specified trace range.
The application can be launched from various modules with input/output capability, Claritas applications, and SeisCAT by selecting a dataset and the qseis option. It also supports SEGY Revision 0 and 1 files, Claritas extended SEGY, and Claritas HDF5 input formats. Besides displaying information, qseis can also be used to modify certain file header values, such as shot, CDP, file fold, primary and secondary keys.
To make edits, users can click the “Allow edits” button, which enables them to modify values displayed in green (editable). Modified values are shown in orange, and changes can be saved by clicking the “Save changes” button to rewrite the binary header of the input file.
