computeCellDistance memory overload

[mckoch234]

d.temp <- computeCellDistance(

•   coordinates = spatial.locs,
  

•   interaction.range = 30,
  

•   ratio = 1,
  

•   tol = 0
  

• )
  

Error: cannot allocate vector of size 1601.1 Gb

Is there a way around this?

The ability of Spatial CellChat to handle large datasets still needs further optimization. At present, you can use the makeGridSpatialCellChat() function to appropriately reduce the dataset size and make computation more manageable; more details about this function can be accessed via help(). We hope this helps resolve your issue.
