netVisual_diffInteraction for each individual cell-type

[abulislam]

Following this tutorial to compare two data-sets

https://htmlpreview.github.io/?https://github.com/sqjin/CellChat/blob/master/tutorial/Comparison_analysis_of_multiple_datasets.html

object.list <- list(OA = cellchat.OA, WT = cellchat.WT)

cellchat <- mergeCellChat(object.list, add.names = names(object.list))

netVisual_diffInteraction(cellchat, weight.scale = T, measure = "count")

above code is giving interactions for all the cell types. But I want to have differential interaction count figure individually for each cell types. For example

netVisual_diffInteraction(cellchat, measure = "count", sources.use="HS1")

Error in i_set_edge_attr(x, attr(value, "name"), index = value, value = attr(value, :
Length of new attribute value must be 1 or 35, the number of target edges, not 19

How can I do that?

thanks

netVisual_diffInteraction(cellchat, measure = c("count"), weight.scale = T, comparison = c(1,2), sources.use = c(11), targets.use = c(1:10))

Needed to define the all other cells as target. Without target specification it doesn't work on all.
