Hi. I get the following error message: limit on number of grids has been reached *** NOTE: tm intern err: netCDF grid w/ static axis This problem is discussed in the ferret FAQ, and the fix is to modify the netcdf file. But, I don't want to do this each time I have a new netcdf file. In my case, the error message comes out only when I rerun my ferret script several times. After that, the ferret hangs and I have to push control Z then kill the ferret program each time. In the beginning of my script, I cancel everything: cancel mode verify cancel axis/all cancel grid cancel memory/ALL cancel data_set/all cancel variable/all cancel mode metafile From ferret FAQ, I understand that ferret can handle as manay as 250000 coordinate points. I am sure that I use less then 2500000 coordinate points. But, it appears that this coordinates accumulate everytime I repeat my script. Is there anyway to cancel those coordinates points, without restarting the ferret? Thank you. Sang-ki
