[Insight-users] A memory issue

[Ali Mouizina]

Why don't you put your coordinates in the same order as in the definition of
the size variable? --> I would say it's a lack of rigor but it doesn't
change anything to the problem. 

Also, this is not a bug, but wouldn't it be nicer to write 152 instead 
of 'ÿ'? --> 'ÿ' <=> 255 :). My code is much bigger and I can't show it here
that's why I made a small code highlighting my problem ;). 

Moreover, when the dimension of my vector is smaller (512*512*25*125 for
instance), my program works fine, but when the third dimension is bigger
(like 150 it crashes even if the memory has been allocated correctly.)
However if I put ' weight2->GetPixel(pixelIndex_weight);' instead of '
weight2->SetPixel(pixelIndex_weight,'ÿ');' it works fine even for large
dimensions. 

Regards,

Ali

     for (int i=0; i<nb_col; i++){
         for (int j=0;j<nb_ln; j++)
             for (int k=0; k<nb_slice; k++)
                 for (int l=0; l<124; l++){

                     pixelIndex_weight[0]=i;
                     pixelIndex_weight[1]=j;
                     pixelIndex_weight[2]=k;
                     pixelIndex_weight[3]=l;

Kind regards,
