Place the four Himawari MAT files in this directory if you deploy the HTML as a teaching package:

HIMAWARI_SST_Hokkaido_20260601_0100_subset.mat
HIMAWARI_SST_Hokkaido_20260601_0200_subset.mat
HIMAWARI_CHLA_Hokkaido_20260601_0100_subset.mat
HIMAWARI_CHLA_Hokkaido_20260601_0200_subset.mat

In the working MATLAB folder, the scripts expect these MAT files to be in the same folder as the scripts, unless you edit the file paths in run06c/run06d.
