Hi, I am currently running into the following problem: when I try to choose the cells along my trajectory using Monocle3, I get an error message "Error in igraph::shortest.paths(g, v = starting_cell, to = end_cells) : At core/paths/dijkstra.c:124 : Weight vector must not contain NaN values, Invalid value". Does anyone maybe know how to fix this issue? My dataset is originally analysed in scanpy (python) and then transferred to Seurat (R) and subsequentely Monocle3, if that makes any difference
