how to export peak matrix as an xlsx

[qimiaonnegliguo]

Hello! I have some confusion about the peak matrix.

After using getAvailableMatrices(projFour) I get
[1] "GeneScoreMatrix" "MotifMatrix"
[3] "PeakMatrix" "TileMatrix"

Is there any method to export this PeakMatrix as an xlsx? It seems getMatrixFromProject() is not an option.

Thanks for your time and help : )

No - there is no way to export an excel file directly from ArchR. If you would like to do this, you will need to manipulate the SummarizedExperiment object that ArchR gives you. You will have to Google to figure out how to do that as it is not an ArchR question.

Apologize for the mistake and thank you for your reply. So is there a way to read peak information from ArchrRproject, such as start, end?
