[email protected] pmel. noaa. gov > Sender: [email protected] I just wish to mention another method-- write a NetCDF documents, and apply the USE/ORDER qualifer to repeat the data and show the reversed axis. In Mick's example, once the reversed data read in, we might SAVE the data to a NetCDF data, and after that review it back in with USE/ORDER=X-Y to suggest that the Y axis is reversed. def axis/y=59. 5:49. 5:1/ systems=degrees_north yfer def axis/x=348. 5:362. 5/ npoints=15/units=degrees_east xfer def grid/x=xfer/y=yfer gin file/form=/ col=15/ord=xy/g=gin/var=v test. file fill/lev= v. ! Mick Spillane wrote: In the situation of information input by means of netCDF files this is not much of a trouble. The axis order can be defined in either direction and Ferret will read it and convert axes and data constantly to its favored order. now make a grid to repeat the NORTH to SOUTH data. def axis/x=1:15:1 xin; def axis/y=1:13:1 yin def grid/x=xin/y=yin gin file/form=/ col=15/ord=xy/g=gin/var=v test. file! after that define the tasting to fix it. let yr=14-y [ g=gin] let virtual reality=samplej! now we require to assign the remedied information to the geographic grid. Access the etopo60 data again and validate that all is well use etopo60; contour/over/lev= climbed. Using the SAMPLEI function one can handle an input ASCII file that was gotten EAST to WEST, and most likely SAMPLEIJ could offer to fix data where both axes were non-ferret-preferred.
