# Budding yeast chromatin is dispersed in a crowded nucleoplasm in vivo
# Chen Chen, Hong Hwa Lim, Jian Shi, Sachiko Tamura, Kazuhiro Maeshima, Uttam Surana, Lu Gan
#
# IMOD reconstruction of yeast and chromatin cryotomograms
#
# Revised 20160417; IMOD version 4.8.47 3/17/2016
# This dir contains the minimal number of files needed to reconstruct the tomograms in Chen et. al.
# Note that some of the tomograms need to be binned x2 to facilitate visualization.
1) Make a .st file from the .mrc tilt series and place in the correct dir (see details below).
2) Run etomo from that directory:
   etomo 14oct01a__014.edf
3) In etomo, execute only the following commands.
  Final Aligned Stack: (Create Tab) Create Full Aligned Stack
                       (Correct CTF Tab) Select the right Falcon noise file, Correct CTF, Use CTF Correction
                       (2D Filter Tab) Filter, Used Filtered Stack, Done
  Tomogram Generation: Generate Tomogram, Done
  Post-processing    : Trim Volume, Done
  Clean Up           : optional cleanup, Done

Create .st files as follows:

# The following use the Falcon2_20141217 noise files for CTF correction
