AssertionError: size and positions (lon, lat, depth) don't have the same lengths.

Hi everyone.

I am trying to release particles from a list of lat and long coordinates, but am having trouble getting this to work. I keep encountering this error: "AssertionError: size and positions (lon, lat, depth) don't have the same lengths." I'm not sure why this is happening; my latitude and longitude lists are the same length, and I have specified Depth=None in the model (I'm not using depth for now). Am I missing something?

I am going to attach my code and also the file containing my coordinates. The reason I am releasing particles from specific sites is they represent areas of habitat that my study species presumably disperse from.

Thank you,
Tom

Perhaps not use depth=None, but depth=0 instead? Same for time.

Or, if that doesn't work, use ParticleSet.from_list(), using np.linspace for lon and lat (like particleset.from_line under the hood) and make depth a vector of zeros: depth=[0]*len(particle_lon)

Will give this a shot, thank you!
