Metadata column from which to subset:

Identities to keep:
(Keep it empty and PROCEED to avoid subsetting)

Sample column from metadata:

Cluster/Annotation column from metadata:

Database to use:

Interaction group:

Ensembl dataset to convert gene names from Ensembl ID to Gene Symbol:

Dataset

Only change when input object contains Ensembl ID

"Automatic" works on Human, Mouse and Zebrafish when selecting the corresponding CellChat database

Parameters for identifyOverExpressedGenes:

thresh.pc

thresh.fc

thresh.p

Parameters for computeCommunProb:

population.size

raw.use

type

trim

Parameters for filterCommunication:

min.cells

Parameters for computeCommunProbPathway:

thresh

Parameters for aggregateNet:

thresh

Parameters for netAnalysis_computeCentrality:

thresh

Parameters for identifyCommunicationPatterns:

k_outgoing

k_incoming

Help me choose k (selectK):

Pattern:

k min

k max

nrun

Runs CellChat's selectK (NMF rank estimation) on the current communication probabilities. Choose the k just before the Cophenetic score drops; high Silhouette confirms the choice. Both measures are displayed for the selected pattern (Outgoing/Incoming).
