How to implement Input CODEX data for 'NCEM about ncem HOT 9 CLOSED

from ncem.

Hi @Luosanj ,

links to: theislab/ncem_tutorials#1 (comment)

answering here to keep it better traceable with respect to issues.

May I ask which ncem version you have installed. We only added the cutsom data loader recently, so you might need to update ncem to use it.

Additionally the Codex data we are using in the manuscrip is taken from this manuscript:

CODEX - cancer
Schürch, C. M. et al. Coordinated Cellular Neighborhoods Orchestrate Antitumoral Immunity at the Colorectal Cancer Invasive Front. Cell 183, 838 (2020).

Data can be downloaded from https://data.mendeley.com/datasets/mpjzbtfgfr/1 To run NCEM download the CRC_clusters_neighborhoods_markers.csv and store it to a data directory of your choice.

Hi @AnnaChristina ,
Thanks for your response ! I have uninstall and reinstall the package 'ncem', but the version didn't change which is 0.1.0. What is the right version supposed to be?

Cheers,

I find that in your tutorial the right version for ncem is 0.1.3. Yet I cannot find this version using command 'pip install'.

Hi @Luosanj,

can you maybe try installing it in a new environment. PyPi also shows the correct version here: https://pypi.org/project/ncem/ and it's hard to assess issues in the installation otherwise.

Thanks for answering Anna ! By the way may I ask is there a tutorial on how to run the 'Encoder Decoder with one layer GCN embedding' model mentioned in your paper ? Currently it seems only linear model can be run. Thanks !

you can also use the non-linear ncem models by switching the model type to ed_ncem or cvae_ncem and the respective gnn layer specified. For simplicity, we currently do not provide a tutorial for all the different model set-ups but it follows the same logic and https://github.com/theislab/ncem_benchmarks/tree/main/scripts shows further examples how the different models can be run and hyperparameter suggestions for the different pre-selected datasets.
