Hi, I am getting this result. Setting method to "scaterUMAP" works.

sceObj = runNormalization(
  inSCE = sceObj,
  useAssay = "counts",
  outAssayName = "logcounts",
  normalizationMethod = "LogNormalize",
  scale = F,
  verbose = T
)

sceObj = runSeuratFindHVG(
  inSCE = sceObj,
  useAssay = "logcounts", 
  method = "vst",
  hvgNumber = 2000, 
  createFeatureSubset = "hvf"
)
s
sceObj = runDimReduce(
  inSCE = sceObj,
  method = "seuratPCA",
  reducedDimName = "PCA",
  useAssay = "logcounts",
  scale = T,
  seed = 789,
  nComponents = 30
)

# runSeuratFindClusters
sceObj = runScranSNN(
  inSCE = sceObj,
  useReducedDim = "PCA",
  clusterName = "cluster",
  k = 14,
  nComp = 30,
  algorithm = "louvain",
  seed = 789
)

sceObj = runDimReduce(
  inSCE = sceObj,
  method = "seuratUMAP",
  useReducedDim = "PCA",
  useFeatureSubset = "hvf",
  reducedDimName = "UMAP",
  scale = F,
  seed = 789,
  nComponents = 2
)
