I have several PTM (Polynomial texture mapping) files that I would like to read in either Python or R for visualisation and computing measurements. I'm not sure how to read these files and would like to work with the X, Y and Z coordinates ideally.

Examples are found here: http://palimpsest.stmarytx.edu/integratingdataarchive/Pal1/Acce/

  • 20140220-Pal1-45-Acce-04-50m-127.ptm
  • 20140220-Pal1-45-Acce-04-50m-e.ptm
  • 20140220-Pal1-45-Acce-04-50m.ptm

Background information of how to build and view these files are found here, it is essentially a rayshading technique: http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/ http://culturalheritageimaging.org/Technologies/RTI/

Thanks in advance for any help or pointers in the right direction.

  • Have you tried `PTMphinder` package: https://github.com/jmwozniak/PTMphinder. Reference: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6555389/ – Gautam Apr 06 '20 at 15:33
  • Ah ok this for visualising protein data - sorry these files are different – Bhav Shah Apr 06 '20 at 22:05
