Thank you for your clarification, R.
I am using ‘CentOS’ v6.9 accessed remotely.
I will discuss with our Informatics Hub.

Best wishes

    ?... sorry for the duplicate send/post - forgot to add the subject line 
last time.

    Hello Zola,
    libGl errors like what you listed below - can mean there is an issue with 
the software installed on the system for the graphics card such that it cannot 
use the installed libGl package to display graphics, e.g., missing drivers, 
etc. &nbsp;
    It would help to know what your linux mahine is running, e.g., CentOS7, 
Ubuntu 18, etc. and whether or not you are using it directly or if you are 
trying to login to it remotely from another machine.
    But you or someone else will need administrator or root privileges on the 
machine if it comes to (re)installing software.
    - R.

            External Email - Use Caution        

    Hi Safi,

    you definitely need the inverse tkr_vox2ras transform, that is correct. 
Also your approach in general seems fine, I tried it in R, and I get the 
expected results:

    (My subject is called 'subject1', and I put the created midbrain label into 
'label/mdb.label' in its directory.)

    ---------------
    library("fsbrain")
    library("freesurferformats")

    # load label and apply ras2vox to the coords to get voxel indices
    lbl = read.fs.label("~/data/subject1_only/subject1/label/mdb.label", 
full=TRUE)
    coords = cbind(lbl$vertexdata$coord1, lbl$vertexdata$coord2, 
lbl$vertexdata$coord3)
    mbc = apply.transform(coords, ras2vox_tkr())

    # load the brain volume and mark the midbrain voxels
    brain = read.fs.mgh("~/data/subject1_only/subject1/mri/brain.mgz", 
drop=TRUE)
    brain[mbc] = 255L; # mark the midbrain region in white (full intensity)

    volvis.lightbox(vol.boundary.box(brain,apply = T)/255)
    # see attached image, the white part is the label
    ---------------


    I would check first whether the values in 'mdb_label_inv' and 'mdb_label' 
make sense. E.g., are the former all positive integers, and is the length of 
both matrices equal to the number of voxels in your midbrain label.

    Best,

    Tim
