Doubt about netcdf format generated by the Climate Indices package

[RR-Torres]

Dear colleagues, I'm trying to calculate the SPI index through the python package made available by you at https://climate-indices.readthedocs.io/en/latest/. I was able to perform all the necessary installations and processing described in the guide, but I am not able to open the netcdf file generated through CDO or Grads software. Would you kindly have an indication of how I should proceed? Thanks in advance. Regards, Roger
