From: Wendy on 24 Jan 2010 08:42 Hi all, I am working with bioinformatics toolbox and trying to read in CEL files from a directory. I stored all the CEL file names in a spreadsheet, and the file names are stored in a cell after reading the spreadsheet into matlab. When I try to read the file, the error says the file does not exist, but I am sure the file is in the directory. I wonder if I convert my cell element to string correctly. What might be the reason for the error. DataDir =' '; [CellType, SampleInfo] = xlsread(' .xls'); for i = 1; FileName = mat2str(cell2mat(SampleInfo(i))) celStruct = affyread(fullfile(DataDir,FileName)); end Thank you, Wendy
