Phase 6 error / unwrap

Hey guys, im having a error in the step 6 on StaMPS, maybe somebody can help me:

Error using /
Matrix dimensions must agree.

Error in uw_grid_wrapped (line 68)
grid_ij(:,1)=ceil((xy_in(:,3)-grid_y_min+1e-3)/pix_size);

Error in stamps (line 503)
ps_unwrap

I read the topic and maybe my study area is too small (2x2km aprox) but is a old topic for mt_prep_gamma…

i set parms :
filter_grid_size: 50
unwrap_grid_size: ‘10’
unwrap_time_win: ‘24’

Regards!

I meet the same error, have you sloved it?
