Using Seurat merged object for pseudo time analysis in Monocle 3 #2833
Comments
Hello,
Then perform pseudotime analysis:
Hope it will help. Good luck! |
Thanks a lot! It worked! |
This is very helpful - thanks! We're preparing to release some updates as well to make this a bit easier, stay tuned! |
Beta Monocle 3 support us available on SeuratWrappers on the feat/monocle3 branch. Conversion to and from |
Hi @mojaveazure, I couldn't make the as.cell_data_set command work after installing SeuratWrappers:
It gives me: Error in as.cell_data_set(my_seurat_object) : |
You need to use the feat/monocle3 branch of SeuratWrappers, not the master or develop branches. |
How do I do that?
|
Nevermind! I managed, but when I try to run "learn_graph" from Monocle3 it gives me this error: No dimensionality reduction for UMAP calculated. Please run reduce_dimensions with reduction_method = UMAP and cluster_cells before running learn_graph. Does this mean that it didn't save all the characteristics of the previous merged Seurat object? I could directly run the learn_graph with the cds object resulting from the code above. |
Thank you KinSimon96 for sharing your code. It worked for pseudotime analysis. |
I had to change

I downloaded the develop version of monocle 3 but I still get this error below, any help is greatly appreciated

@mojaveazure , thanks for the update in seuratwrappers, I have a question regarding plotting in tSNE, rather than UMAP? |
@Mohebg1234 same issue Have you figured out how to do it using SeuratWrappers? Or have to do it manually? |
So great, it can even help me at 2022! |
Thank you very much! It works for me, I just had to change preprocess_aux for reduce_dim_aux :) |
hi thanks for your great work. I have a small question. If im working on an integrated Seurat object, should I use 'integrated' instead of 'RNA' assay? Thank you. |
I have an SCTtransformed merged Seurat object and I would like to follow up with a pseudo time analysis. I've seen that last year Seurat didn't support conversion of Seurat objects to Monocle 3 cds because it was still beta. Is this still the case? Which pseudo time analysis that could be compatible with Seurat object would you recommend? I expect my data to be linear rather than branched. Thank you.
