hi, i have below matrix

TFLocus  TargetLocus  InteractionType
AT5G10140  AT1G65480  -1
AT5G11260  AT1G27480  -1
AT5G11260  AT5G53370  -1
AT5G11260  AT1G03630  -1
AT5G11260  AT1G13600  -1

AT5G11260  AT2G05160  -1
AT5G11260  AT2G40170  -1

using the below code from one of member of this website i converted my matrix to an adjacency matrix but the resulted matrix was without column name or rowname while i need these gene IDs as column name and row name in a symmetric matrix then writing the result in a txt file, may some please complete this code for me??? my needed matrix must contain values 0 or 1 please help me kindly thank you the used code fid = fopen('YourFileNameHere.txt', 'rt'); datacell = textscan(fid, '%s%s%d', 'HeaderLines', 1); fclose(fid); TFLocus = datacell{1}; TargetLocus = datacell{2}; all_locus = unique([TFLocus; TargetLocus]); num_locus = length(all_locus); [~, TFidx] = ismember(TFLocus, all_locus); [~, Targidx] = ismember(TargetLocus, all_locus); adj_matrix = accumarray([TFidx(:), Targidx(:)], 1, [num_locus, num_locus]);
