hi,

i am trying to build vtk version 8.2.0 with Module\_vtkDICOM : BOOL = ON from cmake gui with python wrappings, i have a few doubts,

1. even though i have Module\_vtkDICOM : BOOL = ON in the cmake gui, when i run “make” in terminal, the vtkDIOCM module is not building. How to build with vtkDICOM?

2. i have set the python path to anaconda python 3.6, in cmake as well, even then when i run install the installation path defaults to 2.7 on mac, how to install in anaconda python 3.6 site-packages instead of system 2.7?

Thanks  
Abhishek

Most likely this is due to a known bug in 8.2. See fix here: [Signed vs. unsigned pixel data in DICOMAppHelper](https://discourse.vtk.org/t/signed-vs-unsigned-pixel-data-in-dicomapphelper/955/6)
