question about creating a CosMx object

[CenFWNW]

Hi I have been trying to create a CosMx object using the spateo.io.nanostring.read_nanostring function. I firstly encountered an error

I fixed it by rounding the coordinates to integers.
I then encountered the following error:

Not sure if this error raised by the argument label_columns, buy my cell names are strings in the format c_1_1_1. Also do you have a good guideline of how to use spateo on CosMx data?

Thank you so much!
