R Terminal Aborted and Optimal K not displayed

[Lakshya3141]

Hello. I am trying to implement MultiK on two separate datasets but am running into issues. I shall highlight the issues separately for each dataset:

1. Dataset A with 10k cells. After a long time during which it finishes the reps and moves on to runs for k values, R terminal aborts. This happened every single time, even if I decrease the rep number. I started with 100, however even with a rep number of 8 R terminal aborts. Any optimization I can do at my end to avoid this?

2. Dataset B of 6k cells. R terminal abort experienced as before, corrected by using reps = 10 (all other reps resulted in terminal abort). I am able to obtain the image from DiagMultiKPlot, but running into warnings and optimal K is not shows. The terminal output is:

How shall I resort these errors/warnings?

@Lakshya3141 Hi! I think you will need to run the analysis on a large computing node with more than 10 reps. You will probably need to request more memories for the analysis. For your DiagMultiKPlot() error, can you please show me the image? The error you got is likely due to the number of reps (10 reps is not enough). Hope that helps!
