Dear Christoph,

The *.msk format follows below. I will also send you an email with the access data for our ftp server so that you can download the updated file format documentation, in case you need it.

Best,
Hester

Header
Nr of Bytes: Datatype: Default: Description

2: short int: 3: VTC resolution in mm
2: short int: 57: Start position of x-dimension VTC with respect to VMR
2: short int: 231: End position of x-dimension VTC
2: short int: 52: Start position of y-dimension VTC with respect to VMR
2: short int: 172: End position of y-dimension VTC
2: short int: 59: Start position of z-dimension VTC with respect to VMR
2: short int: 197: End position of z-dimension VTC

Data
Binary array of zeroes and ones of bytes (char) in the positions of the VTC from which the *.msk file is created.

another follow up question...
if the .msk format stays the same.
how does the coordinates correspond to the XYZ in the VOI-details (voxel statistics)?
One scenario would be like this..
the XYZ from .msk file are (57:231, 52:172, 59:197)
but in the VOI details, XYZ are not necessarily in the range of XYZ, for example, the Y goes from 208 to 215. Are those XYZ in the same space?
let me know if my question is not understandable...
Thank you so much!
