I am starting to make sure I can use some basic functions and it seems that the best way at present to transfer data to VMD is by the hdf5 read/write functions. I've been trying to get hdmd5_Write.py to work but this sample file generates an error message:
Traceback (most recent call last):
File "<stdin>", line 35, in <module>
