Different results each time- set seed? #28

Closed krc3004 closed 4 years ago

krc3004 commented 4 years ago

Hi,

I'm trying to use destiny in R and am computing the diffusion map using the dm function with k = 120 on a dataset of roughly 1000 cells. However, the resulting diffusion map looks different every time I compute it, even with the same K. I tried set.seed(100) before running dm but the results are still different. Is there a way to ensure that the diffusion map looks the same every time, or perhaps is there a way to estimate how unstable the data/results are? Thanks!

Please use the version from git master! It works reproducibly.

devtools::install_github('theislab/destiny')
