seurat-wrappers RunVelocity() requested size is too large; suggest to enable ARMA_64BIT

Hello,

I'm having an issue with RunVelocity failing on a 480GB highmem machine (originally tried on 150GB). This seems similar to #21 . I'm not sure I can get a higher mem machine on this cluster. This object is the only one loaded in the session. Any advice would be much appreciated! Thanks!

seurat_combined3 <- RunVelocity(object = seurat_combined3, deltaT = 1, kCells = 25, fit.quantile = 0.02)
