problematic updates or downloads from dbCAN
Hi Jon,
There is a reoccurring error with downloading dbCAN databases from http://dbcan-hcc.unl.edu/download. This is somewhat similar to an earlier issue [https://github.com/nextgenusfs/funannotate2/issues/39](url). During `funannotate2 install -d all` download.json (called line 114 from `install.py`) tries to fetch ...
```
"dbCAN": "http://dbcan-hcc.unl.edu/download/dbCAN-HMMdb-V14.txt",
"dbCAN-tsv": "http://dbcan-hcc.unl.edu/download/Databases/V12/CAZyDB.08062022.fam-activities.txt",
"dbCAN-log": "http://dbcan-hcc.unl.edu/download/Databases/V11/readme.txt",
```
... but this fails from no response by dbCAN, although I can access dbCAN2/3 pages
Perhaps there can be alternative options to fetching the download links using the `download.json` from the funannotate2 github repo, or that there can be a flag for when the files are already locally sourced?
cheers and thanks for the help,
Adam
