Dear David Case ,
I tried to do a tutorial and a run a minimization in TUTORÝAL A2  as you said in order to control the min. process. And I didn’t see anything wrong in TUTORÝAL A2  min.out file . I got the same min.out file in TUTORÝAL A2 . Before I start to use xleap for my n-dodecane simulation  I did the operations below. After all these operations I started the min. , but  I couldn’t get the min.out file. I loaded gaff, a mol2 file and a pdb file and saved all of them as input files. I think I loaded all the information for min. and md simulations. I gave all the information to you about this process. I can’t give any information apart from that. Because that’s all. Now I’m waiting for your help. By the way I want to learn if the red lines I signed in the process is normal or not normal to get.
Many thanks in advance.
