Figure 4-10: File Format dialog box

Here’s what the various parts of File Format dialog box mean:

• File Format — Save in Q-MIPS, XTF, SEG-Y format. Refer to Appendix

B for a description of these formats. SEG-Y format is an Isis option,
available only if it has been purchased for this system.

• Media — Save to a random-access disk or to Exabyte tape. Isis uses

true SEG-Y tape format and a modified SEG-Y format for disk storage.
Disk and Tape Q-MIPS formats are equivalent. Isis can read and write
long file names, not just DOS 8.3 format, to either medium.

• Sample Size to Record — Isis can save 8-bit or 16-bit data. While 8-bit

data storage conserves mass-storage space,16-bit data storage retains
a greater dynamic range. Isis displays 8 bits of imagery.
