Seeking Guidance on Constructing .ins Files for PEST++ with CSV Output

[lrc756866304]

I am a beginner in PEST++ and I am eager to use PEST for calibrating the DNDC crop model. The model's output is in CSV format, but I am encountering difficulties when constructing the .ins file.

For instance, syntax like whitespace skipping (w) and tab instructions (tN) result in errors, while only simple formats such as l2 [var_name]17:25 seem to work. However, I would like to have more flexibility in handling .ins files for CSV manipulation.

I would greatly appreciate any guidance on this matter. Are there any detailed resources that explain how to properly construct .ins files for working with CSV outputs?

Thank you in advance for your help!

I think csv output files are most easily processed with a combination of using the comma as the primary marker and free format to read the values. Here is an example
