Hi @BioinfoTongLI and @dannda
I will really appreciate your input on this issue that I am facing while working on the multi-omics processing webatlas pipeline.
I also met this problem when running the multimodal to combine multiple sections of 10X visum data. Have you tried to set the sort to False? `extend_feature:
path: ./input/STseq_scanpy_cleanSpots_allData.h5ad
args:
sample: ["library_id", "Donor2_Wound1"]
sort: False # The deconvoluted cell type will not be loaded if keeping the default as True. A bit Weired.`
Hi @Zhuang-Bio
Thank you for the suggestion. I am trying it but now my params file is not able to parse. I don't have a cell2location file for spot annotation but I did add a new metadata with the spot annotation as "RCTD_Prediction". Below is the new multi modal config file that was not able to parse. Thank you for your help!

hi @ashishjain1988 , could you please also share the config json file the pipeline generated?
wondering if because the features are named differently in each modality the output json file is pointing at wrong locations
could you also confirm how you tried using the extend_feature_name
param? if the different names are causing issues this would ideally fix it but may not be working as expected
as a sanity check as well, could you confirm in the generated zarr directories there is a cell.idents.L1
directory within obs
for the single cell dataset, and a RCTD_Prediction
within obs
in the visium dataset ?
Hi @dannda
Please find attached the output json file after the webatlas-pipeline multi omics run. I also checked the generated zarr directories and both of them have the respective meta datas (also in the final zarr directory after multi omics run). p262_Multimodal-multimodal-config.json
For the extend_feature_name
param, I created a new metadata in the visum dataset with name cell.idents.L1
and use that as the extend_feature_name
as it is also present in the scRNASeq data.
Thanks @ashishjain1988
I'm trying to figure out where exactly the issue is occurring as I think it is params not being passed properly through the different functions, given that you're getting null
as the feature name
In the meantime, could you try loading with this json instead? I only manually changed where it stated null
as the feature, like "featureFilterPath": "var/is_null"
to the actual names from your data (eg "featureFilterPath": "var/is_cell.idents.L1"
) in case they got written correctly and it was only the config generation that is faulty
Hi @dannda ,
Thank you for the updated file! It worked! I am now able to see the intersected cell types. However, can we also show all the cell types on webatlas in the list (eg. cell types that are specific to one omics type)?
Glad to hear that! On showing all celltypes of one omics type, that can't be done, unfortunately, the multimodal pipeline will compute the intersection so missing data in one modality doesn't come across misleadingly as not expressed/present You could manually force this if you add the data to the modality that does not have it before putting it through the pipeline. Note that for the selection to work correctly across modalities they do need to have the same features even if they are filled with 0s in one of them. If one of them has more or less features, then selection will display the wrong data on them. Or having a separate non-multimodal visualisation for that specific modality only to display its full data
Thank you for the help!
Hi,
I am currently trying to combine my processed Visium and scRNAseq data using the multimodal run. Following the tutorial I was able to process the data and was able to see the combine feature (Gene list) but I am not able to see the combined cell type on webatlas-portal. Here is my multimodal config file that I used to process the data.
url: http://localhost:3000/p262_Multimodal_1/0.5.2/ project: p262_Multimodal title: "Gut data" description: "" outdir: ./output/P262_Multimodal_1
data:
I also tried to rename the cell annotations an try to use extend_feature_name but then I was not able to see even the overlapped gene list. Can you please help me to fix this?
