runPseudotime Error: cannot locate a vector of size 11.9 Gb

[Hgracia]

Hello,

I have this cyt object:
CYT Information:
Input cell number: 62000 cells
Enroll marker number: 42 markers
Cells after downsampling: 62000 cells

It have a memory size of 185.8 MB

The error raises when i follow the # Standard workflow of CytoTree
cyt <- runPseudotime(cyt)
2021-12-14 18:04:07 Pseudotime exists in meta.data, it will be replaced.
Error: cannot locate a vector of size 11.9 Gb

Ussing CytoTree_1.2.0 and 32GB of RAM memory. Seems that something is leaking

I have the same problem. Did you find any solutions yet?
Best greetings

Sorry for the late reply. I think you can try to downsample the input cell number. Thank you.
