Yep I meant that, first you have to select a very very huge area for the tsplot area in matlab and export this very huge CSV table the usual way, then you change to R using the script you found in the documentation to subset the information in an other way than in Matlab, somehow this makes a difference, until now I an still not able to tell why Matlab does not work in this case…
Make sure to adapt the path information to your machine and you need to have a roi to subset your ps of interest, I normally use Google earth to create them… Mostly a but sloppy but it works
