Bigrid Error Messages

  • Error reading line llll of control file.
  • Check line for correct data type.
  • BIGRID failed to read a user supplied parameter given in the BIGRID control file. The parameter either has the wrong type (real value in place of an inte-ger possibly) or was entered incorrectly.
  • INPUT grid structure not correct - run aborted
  • An error occurred reading the grid file header when attempting to re-grid a grid. Either the grid file provided did not conform to the grid specifications or the specified grid file name was incorrect.
  • GRID cell size not given or invalid - run aborted
  • This error results if the grid cell size was not given correctly in the BIGRID control file when gridding XYZ line data. The grid cell size must be given as a positive real number.
  • Error defining grid limits.
  • Check control file limits and XYZ file limits for compatibility
  • If the maximum defined limits are not greater than the minimum limits, then either the parameters xmin,ymin.xmax.ymax were given incorrectly in the BIGRID control file, the XYZ (or input grid file) contained no points within the specified area, or the XYZ file was found to be empty if the limits were determined by default.
  • Some grid values exceed the allowable output grid integer range of +/-32767. Reset the BL and XX values appropri-ately and run the program again.
  • This error occurs when, after converting the real gridded values to the output grid units using the BL and XX values given in line 7 of the BIGRID control file, the converted values are still outside the allowable range. Those values that lie outside the range are represented by dummies in the output grid. For some applications, such as gridding data with a very large dynamic range, this condition may be acceptable.
  • The BL and XX values may be set explicitly in the control file to keep the out-put values within the range.
  • Temporary file too short: bbbb blocks - run aborted
  • On systems that require static allocation for direct access files, the allocated file length (bbbb) was too short to accept all the data supplied. This error should not occur since other limits will be reached before the file limit if properly installed. Allocate more space as necessary.
