I'm wondering whether the cluster information of cells be changed after densvis processing,in other words,how can I get that ? The mapping of colors is required when drawing.
Dear densmap tool,
Any plan for further supporting the newest version of Numba? There are known issues for Numba when running on ARM64/aarch64 CPU structure. Both umap and trimap are now supporting the newest Numba.
Thanks,
Jianshu
I read the paper and wondering how to compute the correlation between the log local radii in the original dataset. Could you let me know which file descripts it?
Hi,
I'm trying to fit the model on a dataset with densmap.fit()
and then to evaluate the embedding on a new dataset with different number of rows with densmap.transform()
but I get an error of "index out of bound" for the row index. Is it a bug or the algorithm, by definition, is not allowed to do out-of-sample prediction?
Thanks
Would you have any objections if I package a (possibly slightly modified) version of this repository in an R package to submit to CRAN? Of course with appropriate credit and citation.
Hi,
How did you generate the synthetic data? I only find a "trial.txt" file here but not the process of generating it. Could you let me know the process of it?
Dear,
I tried to install the package with pip command.
But I couldn't find requirements.txt. Where is the file to install the package?
Thanks.
Unless my input (data) has equal row and column numbers, I receive this error. Am I doing something wrong?

Thanks for all your work -- this looks like a great addition/advancement over the standard UMAP approach. I was wondering if you would consider integrating densmap into the Python UMAP repository? I am currently adding new features in the 0.5dev branch, and I feel like DensMAP support would be a very valuable option to have for many users. If you do not have the time I certainly understand, and I can endeavour to add the feature myself, but I would certainly appreciate PRs from the original authors if possible.
If you do wish to make PRs please make sure to update READMEs and documentation to include citations/references to your paper to ensure proper credit.
I met a ZeroDivisionError. It is very confusing.

I have an issue installing densvis (and the parent package scater) on M1 apple silicon.
It appears another user has an identical issue, so Id don't see the need to produce a working example.
Probably related to fortran, macOS, homerbrew etc.
I"m running densMAP in the development version of Seurat, and it seems to work (hallelujah!) but the clustering is not reproducible. If I run the same pipeline twice over, the clustering is similar yet different. Is there a way to make it reproducible?
setting the seed doesn't help. Is this intrinsic to the densMAP algorithm? Or is there a way to make it reproducible?
thanks,
Nicolaas
ps command I run is:
