Warning messages about data length differs from size of matrix

[coralzhang]

I tried demo code using the pbmc_small object, using the following code

` newFiles=Improved_Seurat_Pre_Process(seuratObject=pbmc_small, num_genes=50, write_files=FALSE)

 write.table(newFiles$newExpressionFile, paste0(filename,"exp"), sep="\t")

 write.table(newFiles$newGroupsFile, paste0(filename,"grp"), sep="\t", col.names = F)

 filename="PBMC_example"

 location=output_dir

results=Main_Doublet_Decon(rawDataFile=paste0(filename,"exp"), 
                        groupsFile=paste0(filename,"grp"), 
                        filename=filename, 
                        location=location,
                        fullDataFile=NULL, 
                        removeCC=FALSE, 
                        species="hsa", 
                        rhop=0.7, 
                        write=TRUE, 
                        PMF=TRUE, 
                        useFull=FALSE, 
                        heatmap=FALSE,
                        centroids=TRUE,
                        num_doubs=10, 
                        only50=FALSE,
                        min_uniq=4,
                        nCores=-1)

` Then I got the following warning message, not sure if it means anything wrong? Loading packages... Reading data... Processing raw data... Combining similar clusters...
