When multiple dates of altimetry datas are combined in a single file about py-eddy-tracker

Hi,

To specify a non-coordinates index you could read this docstring GridDataset, you need to use indexs option.
If you choose this solution you will need to apply manually all operation describe here : filtering(if wanted), identification, storage

If you split in several files you could also use directly EddyId.

Thanks,

To test this I've build some new files. So i have one one hand, individual daily files, and on the other hand a single file concatenated from the others using NCO tools, along a (now) record dimension "time".

While I was loading individual files as such before :

g = RegularGridDataset("../l4_cmems/dt_blacksea_allsat_phy_l4_"+dat1+"_20200801.nc", lon_name, lat_name)

I now attempted to load a slice from the concatenated file as follows :

g = GridDataset(filename="../l4_cmems/dt_blacksea_allsat_phy_l4_201404_20200801_tr.nc",
                x_name=lon_name,
                y_name=lat_name, 
                indexs={'time':23467})

which results with the error :

~/.pyenv/versions/3.8.3/lib/python3.8/site-packages/pyEddyTracker-3.2.0+0.g775b28f.dirty-py3.8.egg/py_eddy_tracker/dataset/grid.py in __init__(self, filename, x_name, y_name, centered, indexs, unset)

    418 
    419     def setup_coordinates(self):

AttributeError: 'GridDataset' object has no attribute 'init_pos_interpolator'

Is there a missing update of the 'GridDataset' function, or am I not setting the indexs argument correctly ?

Thanks !

Sorry, i was not explicit you must still use RegularGridDataset, just i give you help of GridDataset because RegularGridDataset inherit from: doc of RegularGridDataset
