GUIEditSegyHeader is a GUI for editing the SEG-Y header.
[Data,STH,SH]=ReadSegy('841_m.sgy');
SH=GUIEditSegyHeader(SH);
From this GUI it is possible to view and edit the Textual File Header (Section 6.3, “Editing the SEG-Y header”)
GUIEditTextualFileHeader is a GUI for viewing the textual file header (either in ASCII of EBCDIC format) [editing is not yet implemented].
[Data,STH,SH]=ReadSegy('841_m.sgy');
SH=GUIEditTextualFileHeader(SH);
This GUI is integrated into GUIEditSegyHeader(Section 6.3, “Editing the SEG-Y header”).
