MTtmax6000_N1000000_k+0.1_k-T0.001_k-D0.1_kh1.txt
# nMT=1000000 tmax=60000 trelax=10000 k+=0.1 k-T=0.001 k-D=0.1 kh=1

I tried to read these data by using dlmread, txtscan or textread when I implement the code I receive this massage:
Error using dlmread (line 139) Mismatch between file and format string. Trouble reading number from file (row 1u, field 1u) ==> # nMT=1000000 tmax=4000 trelax=1000 k+=1 k-T=0.01 k-D=0.1 kh=1\n
I want order to read txt files and ignore two first rows.Any help would be greatly appreciated. I will be grateful to you.

With textscan you can use the HeaderLines name-value pair to skip the first two rows:
textscan(fid, formatspec, 'HeaderLines', 2);
