Grid operations display the following error message:
Error: "FATAL ERROR MSEEK: Invalid Argument while accessing file (seeking to position -2147483648 of -2147483648 for read): /path/to/grid/w001001.adf Bailing out of GRID FATAL ERROR Unable to re-open output file (P23RCV)"
The grid's w001001.adf file has exceeded the maximum file size allowed by 32 bit software applications of 2.147GB (2exp31 - 1).
Solution or Workaround
- Process the data in several smaller pieces.
Use AML reserved Grid variables to set the analysis window to a subsection of the original grid's extent. For example:
Code: &DESCRIBE ingrd SETWINDOW %GRD$XMIN% %GRD$YMIN% ~ [CALC %GRD$XMIN% + ( ( %GRD$NCOLS% / 2 ) * %GRD$DX% )] ~ [CALC %GRD$YMIN% + ( ( %GRD$NROWS% / 2 ) * %GRD$DY% )] lowerleft = ingrd
This SETWINDOW syntax sets the analysis window to the lower left quadrant of INGRD. With this window set, the LOWERLEFT grid is created directly from the INGRD cells in that window.
- Reduce the resolution of the data. Use the Grid commands SETCELL or RESAMPLE.
