Hello Community, I have a problem with the InVEST coastal **blue** carbon model output. I was able to successfully run the model, but I got value of net carbon sequestration “0” some categories LULC. Please give me some solution. Here with I have attached log file

Hi @Karthi -

It looks like you’re running a very old version of the model (3.3.2) - can you try [the latest version (3.7)](https://naturalcapitalproject.stanford.edu/invest/)?

Aside from that, which LULC categories have sequestration values of 0? Are they ones you are considering blue carbon habitat, or ones that are not habitat?
