How long does it take to convert MRCP phantom in obj format to .ele and .node format? #3

I tried to convert MRCP to .ele, but it took about 20h and a lot of memory to complete, and the programme didn't report an error!

Hi,

When I used my intel i7 core (2017), it took less than 10 minutes. It was also the same in my laptops.

Best regards, Haegin

Thank you very much for your reply, your code is very helpful. My phantom is from ICRP145 and unmodified, the conversion using POLY2TET is not successful, it keeps repeating the following. Is it a mesh phantom problem or which parameters need to be modified？

I see. Can you please run the code by including -s option? The -s option sometimes solve this issue.
