Problem running octave plmDCA.m test_data/T1019s2.aln

[Maj18]

Hej, I tried to run plmDCA.m test_data/T1019s2.aln, but I got the following error:
octave: no graphical display found
octave: disabling GUI features

N = 88 B_with_id_seq = 393 B = 393 B_eff = 393.00 q = 22

Minimizing g_r for node r=1
warning: non-integer range used as index

plmDCA>g_r at line 212 column 8
plmDCA>g_r at line 215 column 23

plmDCA>min_g_r at line 206 column 7
plmDCA at line 91 column 15
error: reshape: SIZE must be non-negative
error: execution exception in plmDCA.m

I don't use matlab, so can't really fix the problem. Can you please help me out? Thank you!
Maj

you can try octave --no-gui -W plmDCA.m $aln for solving your problem.
