cadnano2.5 not running on Windows 10 after installation

[blackwellbert]

After installing according to instructions and using the command "cadnano" in dos shell from cadnano2.5 directory, I get the following output:

C:\Users\pparr\OneDrive\Documents\GitHub\cadnano2.5>cadnano

TypeError: arguments did not match any overloaded call:
QFont(): too many arguments
QFont(str, pointSize: int = -1, weight: int = -1, italic: bool = False): argument 2 has unexpected type 'float'
QFont(QFont, QPaintDevice): argument 1 has unexpected type 'str'
QFont(QFont): argument 1 has unexpected type 'str'
QFont(Any): too many arguments

However, when I run the command "cadnano2' from the same directory, cadnano2.4 runs. So why does the 2.4 version run but not the 2.5 version as shown by the errors above? Or am I missing something?

Thanks in advance for your help!

In general, we probably need to start working on porting cadnano2.5 over to PyQt6.

In the meantime, I think this particular bug can be fixed by casting the QFont parameter as an int — I saw similar behavior with cadnano2.

I’ll try to take a look within the next week or so.

Thanks for your email! Is it possible to use “autobreak”? If so, how do I activate it?

The old algorithm did not select very good break positions, so we removed it to encourage users to break staples manually. Our lab has been building a new algorithm that gives even better results, based on applying a global optimization to minimize scaffold looping entropy. This is not yet published, but I hope to launch it as a web-based tool in the coming months, where you will be able to upload cadnano files and apply the algorithm to perform a highly optimized autobreak.

In the meantime, I recommend breaking manually using the the "Rule 3" heuristic from this paper:

Thanks for the info! I will check it out!

Any news about the AutoBreak? Either in Cadnano or the web-based tool? Thanks.
