Questions about creating pertdata with own data files

[HelloWorldLTY]

Hi, thanks for your work. I wonder if it is possible for us to access the sample_adata.h5ad file in the dataset tutorial. I intend to test if creating dataset functions have other errors or not. Thanks.

Moreover, I found that I met nan when training GEARs with own datasets

What could be the possible reasons? Thanks.

Can you provide more details on what dataset you are using for training. Did you use the data tutorial as is or did you make modifications

Very likely this is a problem of data normalization or maybe there are zeroes or nans in your data

Hi, I used datasets from this paper (https://www.biorxiv.org/content/10.1101/2024.07.03.601903v1.abstract) which contains two large-scale perturbation datasets. I follow the recommended pre-processing step and verify that there are no nan values.

Thanks.
