How to resolve the issue?

Dear all,
Good morning,


Traceback (most recent call last):

Kindly advise. Thank You.

You'll need to provide more details on when this happens, what you are trying to do. One can guess, maybe, from the errors, but not really pinpoint anything. Does the string "(8R,9" have some relation to the name of a stash item (configuration) in the Builder? If so, maybe try to rename it.

This is coming when - 1. I want to make a normal CNT Device from bulk (Especially for electrode expansion for example 4.56 Angstrom to 25 Angstrom)
)
2. I want to download the target molecule from Pubmed CID for the sensing application
3. I Want to delete something from the stash.

Thank You.

Maybe your stash has become corrupt. You can start fresh by deleting the file Builder_Stash.hdf5 in the project (or just rename it, maybe some data is needed and can be saved later).
