Error in mae or pdb reading

[Xinheng-He]

Hi!

I'm currently using dabble to produce structures and my configuration is based on conda install -c rbetz dabble in python 3.6.3.

However, when I try to read pdbs or maes, the problem is raised:

Inferring output format from file extension
Traceback (most recent call last):

atomsel('all', molid=molid).beta = 1
AttributeError: 'atomsel.atomsel' object has no attribute 'beta'

It seems that from vmd import atomsel shows some error that 'atomsel.atomsel' object does not work well. It there any solution?

Thanks for your concerning and wish to get a reply.
