I am working on tissue heterogeneity and would like to add conductivity values per node rather than per tag region. I saw the -adjustment option but this seems to only accept ionic modifications by means of an input file. Is it possible to do something similar for conductivity values?

Thank you!

Sorry, nodal conuctivities are currently not supported and would require significant effort to implement.

The closest thing to what you are suggesting, are the -gi_elem_vec and -ge_elem_vec options where you can pass (per-element) scaling vectors that will be applied to the intra- and extra-cellular conductivites.

This still allows for complex conductivity gradients, but defined on the elements not the nodes.

Hi , Thanks for this earlier answer. I was going through  the example titled , Concept: regions vs. gradients (  The example has been very well explained and i have been able to run the file too but what i really want to implement is a gradient of conductivities instead of a gradient of ionic cellular parameters (I want to prescribe a gradient of conductivity instead of regions of conductivities)

Can you please offer some guidance on how can i do it using gi_elem_vec or ge_elem_vec ?

I would be thankful for your kind guidance/response.

Best Regards,
