I want to select the variable at different(non-sequential) time steps using a "let" command (say at l=2, l=5, l=9, l=11, l=15, 18, l=20). Is it possible to do this in ferret?
currently SET data sets:
name title I J K L M N
SST Monthly Mean of Sea Surface Tem 1:360 1:180 ... 1:27 ... ...
let sst_new=sst[l=2, 5, 9, 11, 15, 18, 20] ! I tried it in this way, but doesn't work
