7 years ago Hi @SAMPHY86 ! Thank you for the issue! In fact it was already fixed in the master branch but not yet released. Now I've released version 0.5, you can download (or install directly with pip) from here: https://github.com/nansencenter/sea_ice_drift/archive/v0.5.tar.gz
Hi, I tried running sea_ice_drift with the supplied test data but cannot get it to work. The Feature tracking seems to be fine (the figure looks as in the example at the website), but the pattern matching doesn't yield any results. Could anyone read through the output below (especially the very last line) and hint me in a direction what the trouble is? Very much appreciated, many thanks, Usama.
