I also get the same error. According to cytotalk.R, line 104, vec_nst_a <- nonselftalk(mat_a, lrp) returns error message. Matrices must have same dimensions in e1 + diag2Tsmart(e2, e1, "d") In my case, mouse sample is used for analysis. Below is my command. ################## GPC1 <- subset(x = seuratObj, idents = "GPC1") GPC1_mat <- as.matrix(GPC1@assays$integrated@scale.data) common_genes <- intersect(CytoTalk::pcg_mouse, rownames(GPC1_mat)) GPC1_mat <- GPC1_mat[common_genes,] GPC1_mat <- na.omit(GPC1_mat) write.csv(GPC1_mat, file="~/single/cytotalk/scRNAseq_GPC1.csv")
GPC2 <- subset(x = seuratObj, idents = "GPC2") GPC2_mat <- as.matrix(GPC2@assays$integrated@scale.data) common_genes2 <- intersect(CytoTalk::pcg_mouse, rownames(GPC2_mat)) GPC2_mat <- GPC2_mat[common_genes2,] GPC2_mat <- na.omit(GPC2_mat) write.csv(GPC2_mat, file="~/single/cytotalk/scRNAseq_GPC2.csv")
lst_scrna <- CytoTalk::read_matrix_folder("~/single/cytotalk") table(lst_scrna$cell_types)
cell_type_a <- "GPC1" cell_type_b <- "GPC2"
results <- CytoTalk::run_cytotalk(lst_scrna, cell_type_a, cell_type_b, pcg = CytoTalk::pcg_mouse, lrp = CytoTalk::lrp_mouse) ################## I think index <- which(Matrix::rowSums(mat_type != 0) == 0) makes error in my case. Is it necessary to scale each data after subset?
Hello! I am trying to am trying to run CytoTalk to find out cell-cell interactions in my data that I obtained using
cellphonedb
. Hence, I have two matrices: one with the counts (format_counts.txt) and another with the metadata (forma_meta.txt) that maps the cell types to columns. The count matrix contains 5790 cells (columns) and 10570 genes (rows), along with the corresponding 5790 cells in the metadata file.I am loading the data as follows and when I am trying to run
run_cytotalk
I get this error:`fpath_mat <- "format_counts.txt" fpath_meta <- "format_meta.txt" lst_scrna <- CytoTalk::read_matrix_with_meta(fpath_mat, fpath_meta) table(lst_scrna$cell_types) type_a <- "Inh_1" type_b <- "Inh_1" results <- CytoTalk::run_cytotalk(lst_scrna, type_a, type_b)
` Could you please help me figure out what is going on?
