Hi @Nayanathara -

First, can you try using the latest InVEST, version 3.7? That has a lot of bug fixes since 3.5, and this problem might go away. If you still get the error, let us know - thanks!

Hi @Nayanathara -

Would you please post the logfile (.txt) that the model produces? It might give us an idea if something is going wrong. Thanks!

Hi
when i running InVEST carbon model version 3.7, model completed successfully. But my output tif file (c_above_cur, c_below_cur, c_dead_cur and c_soil cur tif files) didn’t open. can you give me the reason behind from this.

Hi @Nayanathara -

When you say that the output files didn’t open, do you mean that you tried to view them in a GIS but couldn’t? Or something different? Please give us more information about what you were trying to do that didn’t work. Thanks.

Hi @Nayanathara -

That error is saying that there are Values in your land use/land cover raster (85, 89, 189, 227 and 255) that do not have rows in the carbon pool table. So first, check to make sure that those values have corresponding lucodes in the carbon pool table.

If those values are already in the carbon pool table, check the table itself. The values in it must be separated by commas, not semicolons or any other character. You can’t see this in Excel, so open the file in a text editor.

Also, it is very helpful if you post the entire log file (.txt) that the model produces, not just the final error. Sometimes there is additional information in the log file that can help troubleshoot.

Thanks for posting the log file. Did you also verify that those land use raster values are also in the carbon pool table, and that the format of the table is correct?
