[Insight-users] Failed to allocate memory for image

[Luis Ibanez]

Hi Ashish,

What version of ITK are you using ?

   This looks like a memory leak...

Note that you really don't have to create
the reader an the GDCMImage IO at every
iteration of the loop. That being said,
your code is still a valid construction.

Do you get the same error if you suppress
the code that is "oprocessing information from
header of each image" ?

It may be that that section of code contains
a memory leak...


   Please let us know


      Thanks


          Luis
