Hi Diane,
Ferret automatically "strides" the data when doing a text listing, making it convenient to just get a look at the numbers without the listing wrapping around on the screen. The qualifier LIST/WIDTH= lets you set the length of the row, in order to write out all of the data, so just make that big enough to list all the data. You could also look at setting the precision used, though the default precision already gives only a few digits of precision.
Another kind of listing that's often more useful is one with longitude, latitude, variable (in the case of a 2-D variable). Define 2-D variables which are the longitude at each x,y location and latitude at each x,y location:
yes? let xlon = x[gx=var] + 0*y[gy=var]
yes? let ylat = 0*x[gx=var] + y[gy=var]then unravel these into 1-D lists, giving them titles and units so the file gets a useful header,
yes? let/units=degrees_east/title="longitude" xpts = xsequence(xlon)
yes? let/units=degrees_north/title="latitude" ypts = xsequence(ylat)
yes? let/like=var var_xy = xsequence(var)yes? list/norow/clobber/file=output.dat xpts, ypts, var_xy
Similar things can be done to unravel grids with more dimensions.

Hello everyone,
I was trying to extract section data from a gridded netcdf file for plotting and also to get raw data. However when I use LIST, it only displays the data points for every other longitude/latitude on the section. Is there a limit to the number of points which Ferret can display? Or is there a command to make sure that it displays data for all points?
Would appreciate any suggestions. Thank you very much!
