With an ascii file like this, i should create an array without char and replace -9.99e+08 by NaN. I have tried to use fscaf, importdata, fopen, fgetl, textscan, with no luck. Data is about 2700x120

Hello Rapha alpha,
Try for this code..
clear all;
contador=1;
fid = fopen('ascii_file.txt');
tline = fgetl(fid);
while ischar(tline)
disp(tline);
if (tline ~= -1)
if ~isempty(tline)
nums(contador,:) = {strrep(tline,'-9.99e+08','NaN')};
end
else
nums(contador,:) = {''};
end
contador = contador + 1;
tline = fgetl(fid);
end
fclose(fid);
fid = fopen('ascii_file.txt','w');
for i=1:length(nums)
fprintf(fid,'%s\n',nums{i});
end
fclose(fid);
