Cholmod error 'problem too large' after cell simulation

[christinedien]

Hello,
I have run into an error when using the trying to simulate larger datasets with the branching backbone. The smallest dataset I have had this issue with so far is: 5000 cells x 6000 genes.

I am generating the cells with: num_simulations = num_cells / 10

The error appears after the "Running x simulations" step has finished, likely some where around here

dyngen/R/6_simulation.R

Line 74 in 37fd179

counts = do.call(rbind, map(simulations, "counts")),

Error in .rbind2Csp(x, y) :
  Cholmod error 'problem too large' at file ../Core/cholmod_sparse.c, line 89

Thanks!
