Where to store obo file

[Tim-Kirkwood]

Hello,

Thank you for making this tool.

I am trying to replicate this usecase with this command on Windows 11, Python 3:

python C:\Anaconda3\pkgs\goatools-1.2.3-pyh7cba7a3_2\python-scripts\plot_go_term.py --term=GO:0055013,GO:0060048,GO:0003300,GO:0055008,GO:0055003,GO:0035995,GO:0007076,GO:0006936,GO:0010628,GO:0050714,GO:0010737,GO:0051592,GO:0045214,GO:0048769,GO:0030241,GO:0030240,GO:0006941

I get this error:

Traceback (most recent call last):

    raise Exception(

download obo file first
 [http://geneontology.org/ontology/go-basic.obo]

As I am on Windows, I cant use wget. Therefore, I manually downloaded the go-basic.obo file and put it in C:\Anaconda3\pkgs\goatools-1.2.3-pyh7cba7a3_2\site-packages\goatools. This is because it looks like OBOReader expects the obo file to be in the same location as the obo_parser module. However, I got the same error.

Can I confirm where the obo file should be placed? Please could you suggest any other potential fixes?

Thanks very much!

For this script and most other cases, the obo file should be placed in the current working directory.

For example, let's say you download the obo to /tmp, then you can just run the script there.

$ ls -1 *.obo
go-basic.obo

$ plot_go_term.py --term=GO:0055013
