Clustering with SIMLR

This function executes a ubuntu docker that produces a specific number of permutation with SIMLR clustering.

simlrBootstrap(
  group = c("sudo", "docker"),
  scratch.folder,
  file,
  nPerm,
  permAtTime,
  percent,
  range1,
  range2,
  separator,
  logTen = 0,
  seed = 111,
  sp = 0.8,
  clusterPermErr = 0.05,
  maxDeltaConfidence = NULL,
  minLogMean = NULL
)

Arguments

group,

a character string. Two options: sudo or docker, depending to which group the user belongs
scratch.folder,

a character string indicating the path of the scratch folder
file,

a character string indicating the path of the file, with file name and extension included
nPerm,

number of permutations to be executed
permAtTime,

number of permutations computed in parallel
percent,

percentage of randomly selected cells removed in each permutation
range1,

beginning of the range of clusters to be investigated
range2,

end of the range of clusters to be investigated
separator,

separator used in count file, e.g. '\t', ','
logTen,

1 if the count matrix is already in log10, 0 otherwise
seed,

important value to reproduce the same results with same input
sp,

minimun number of percentage of cells that has to be in common in a cluster, between two permutations, default 0.8
clusterPermErr,

probability error in depicting the number of clusters in each permutation, default = 0.05
maxDeltaConfidence,

max value for Delta confidence for genes feature selection
minLogMean,

min value for Log mean for genes feature selection

Value

A folder Results containing a folder with the name of the experiment, which contains: VioPlot of silhouette cells value for each number of cluster used, a folder with the number of clusters used for SIMLR clustering, which contains: clusterP file with clustering results for each permutation, killedCell file with removed cells in each permutation, clustering.output a sommarize file with general information for each cells
