The code is trying to access objects that does not exist in the dataset

Hello,

I'm trying to understand and use Signac. I tried the tutorial with a sample dataset explained here "https://htmlpreview.github.io/?https://github.com/mathewchamberlain/SignacX/master/vignettes/signac-Seurat_pbmcs.html". The initial steps were running fine until the "Signac()" method was called. However, during the runtime, the method is raising the following error "Error in E@graphs[[1]] : subscript out of bounds". Which seems to be because it was trying to access objects that do not exist in the data. It would be really appreciable if someone could look into this.

Thank you Mohan
