Problem generating mds plot after repOverlap about immunarch

[peter-yufan-zeng]

Replacing the NA's still throws error

Error in MASS::isoMDS(.data, k = 2, trace = F) : zero or negative distance between objects 1 and 2

Hi @peter-yufan-zeng

sorry for the late response! Is it possible to replace NAs and try again if it works?

res = repOverlapAnalysis(imm_ov1, "mds+kmeans")
res[is.na(res)] = 0

Ping about the repOverlap MDS issues @peter-yufan-zeng

Thank you, will look into this as well. Thank you a lot for coming back and helping us improve the package, @peter-yufan-zeng !

[peter-yufan-zeng]

@vadimnazarov no problem. I am a huge fan of the package and appreciate your help 👍

Hi, I tried to reproduce it on the dev version of immunarch and test data data(immdata), but I don't have any problems. Could you share the overlap matrix here? What version of the package are you using?
