Re: [ferret_users] Got "no valid data" with eofsvd

[Jian Ma <jianma@xxxxxxxxxx>]

Hi All,

I figured out the reason. It is because I have t step filled with missing values. While this is not any problem with the old version ferret with eof_*, it is with newer version ferret with eofsvd_*. I guess this should be reported as a bug. Currently the only solution for me may be to move the time steps and remove the missing value t steps from the data.

Hi All,

I met a strange problem with eofsvd for the attached data file. It turns out to be "No valid data". Here is my commands:

yes? set d sstappcf_ma.nc 

yes? fill/l=1 sstappcf_ma

yes? let exyt=eofsvd_space(sstappcf_ma)

yes? fill/l=1 exyt

However I got good results with a data file with time coordinate dd-mm-yyyy. This file has only 1:22 in t coordinate without actual dd-mm-yyyy. Is this the reason for the problem?

Many thanks for any hint,

Tony
