graph datasets

Hi,
I could not find the graph classification datasets Mutagenicity and NCI1 in the repo. Could you please point me. Also, when loaded from the ckpt folder, each graph of Mutagenicity dataset have [100,100] dense representation of Adj matrix. According to my findings, some graphs in Mutagenicity dataset have variable number of nodes in a graph some exceeding 100 nodes per graph. In that case the Adj matrix will not [100,100]. Could you please also share how the dense representation of Adj was created. Thanks in advance.

Hi,

GNNExplainer use a fixed graph size of 100 nodes and skips all graphs that have more than 100 nodes. We use GNNExplainer's code to process the dataset and train the graph classification model. Then, we save the processed dataset and graph classification model parameters into the checkpoint. In orphicx, we directly load the checkpoint and then train our explainer.
