som

Hi Experts, I am working on Self Organizing Map (SOM) Implementation and i have a microarray dataset which i am trying to read in using some_read_data function, but i keep having an errors when i edit it to have it in SOM_PAK form which is recognise by SOM for reading such as

??? Error using ==> somtoolbox\som_read_data.m Only 69 vector components on input file data line 1 (dimension is 70)

Error in ==> SomMainFunction at 3 sD = som_read_data('B_r2.txt');

but when i try to read the data without editing which is the original file as shown here: http://rapidshare.com/files/376239367/DLBCL.txt.html

It indicates "Data read OK", but i have the following error

??? Error using ==> unknown Out of memory. Type HELP MEMORY for your options.

Error in ==> somtoolbox\som_bmus.m at 189 Bmus = zeros(dlen,length(which_bmus));

Error in ==> somvis\somvis_p_matrix.m at 41 [dummy dists] = som_bmus (dat, dat, 2:datlen);

Error in ==> SomMainFunction at 16 [pheight rad_real perc] = somvis_p_matrix(sM,sD);

You can get the datafile from here:http://rapidshare.com/files/376239367/DLBCL.txt.html

I need someone to help me correct this data for me and put it in SOM_PAK format. I have tried getting it in SOM_PAK format, but it still giving me errors:
