Dear Dr. Yates,
Firstly, I would like to express my excitement in following your
work closely. In my doctoral thesis, I conducted morphometric
analyses on rats with Alzheimer's using the Quint workflow.
However, due to concerns raised by my committee members regarding
this workflow, I received feedback for revisions. I aligned images
with an atlas template using QUICKNII and VisuAlign and performed
volumetric analyses stereologically. Nonetheless, my committee
members pointed out potential shrinkage or displacement during the
histological preparation of samples, questioning the validity of
manually fitting them to the template.
They particularly expressed concerns about errors that could arise
when placing small neuroanatomical areas onto the template. They
questioned how the program distinguishes local features in areas
where histological boundaries are not clearly defined, even in
stained sections. They inquired about the methods used in Quint
workflow to validate measurement accuracy and requested information
on error coefficients or standard deviations in these measurements.
Furthermore, they highlighted that tissue blocks may not perfectly
align with the x, y axes during sectioning by a microtome, raising
questions about how axial shifts affect the placement of atlas
templates and subsequent measurements.
They also asked about integrating 2D histological images into a 3D
atlas and how this process ensures accuracy. Despite referencing
your team’s research and providing explanations, they remained
unconvinced.
Could I please ask for your assistance in addressing these
concerns? Your guidance in this matter would be greatly
appreciated.
Best regards,
Threaded View
