Dear all, I am using coot 0.6.2 on MacBook. It was working nicely when I was using previous version. With this new coot I am problem as I can not do anything except visualisation. If I try to build or refine always show the message "refinement setup failure, Failed to find restraints" or "missing dictionary". I reinstall the coot but still have the same problem. I was not able to locate the dictionary. Can please anybody suggest me something, how to solve the problem. Thanks in advance Md.
