Question about the use of read_nctiles

[GC0225]

I have copy the update commit 'read_nctiles', but when I read the variables to calculate the volume budget like this:
oceFWflx = read_nctiles( [dir1,'oceFWflx/','oceFWflx'],'oceFWflx',ii )
It will show that '/ECCOv4r4/nctiles_monthly/oceFWflx/oceFWflx.0001.nc not found in the current directory'.
Actually, I noticed that the file named by oceFWflx.0001.nc didn't exist in the ECCOv4r4, in which the files are stored in sub-directories of different year and named by the months, rather than divided into 13 tiles like v4r3.
So how can I solve it and read the variables successfully to calculate the volume budget with v4r4?

@bitterground I can use the updated read_nctiles in PR #17 to read V4r4's files (organized by year and month) without issue (see below). Could it be in your case somehow the path is not specified correctly?

dir1='ECCO/Release4/nctiles_monthly/';
ii=3;
oceFWflx = read_nctiles( [dir1,'oceFWflx/','oceFWflx'],'oceFWflx',ii)
