 Dear All,

I am new to NFT. I downloaded the latest version on my 16 gb Win7

optimset reference page in the documentation for a list of
acceptable option parameters. Link to reference page.
Error in segm_inhomogeneity_correction>BiasCorrLEMSS2D (line 768)
                option = optimset('TolX',1e0,'Display','off',...
Error in segm_inhomogeneity_correction (line 54)
B = BiasCorrLEMSS2D(If, Imask.*ImaskClean, bck_mean, bck_std, options, data_B0);
Error in Segmentation>pbinhomog_Callback (line 1168)
[B, B0, Ic, ImaskClean] = segm_inhomogeneity_correction(I0);

Error while evaluating uicontrol Callback

It looks that NFT uses an earlier optimset version not compatible with
v6.4 toolbox. Proceeding with segmentation, all seems to work OK with
no errors, but I do not know how the initial error affects the whole
