== Abstract ==

Background CryoEM has gained popularity due to advancements in both hardware and software, making it possible
to visualize biological molecular structures in detail. However, despite its growing use, cryoEM remains a costly
technique, and limited access to cryo-capable TEMs is slowing research efforts. By refining experimental design
and streamlining data collection approaches, researchers can significantly boost efficiency and reduce costs, making
this technique more accessible and impactful.
Method This work presents a guide to some of the session setup parameters for automated cryoEM data collection
using Thermo Fisher’s EPU software.
Results The TIFF and MRC formats were compared, and the Faster acquisition mode was evaluated against the Accurate
acquisition mode. Acquired TIFF files were significantly smaller than MRC files without any notable loss of resolution
in the data. By minimizing stage movements, the Faster acquisition mode increases data collection speed,
while Accurate acquisition provides precise centering on the optical axis. The models generated from all experiments
exhibit similar resolutions, approximately 2.12 Å. These findings suggest that the Faster mode, coupled with recent
advancements in hardware and software, can increase data collection speed by nearly 5 times.
Discussion This guide offers practical insights into optimizing data collection strategies based on the study’s target
and sample nature. Such optimization ensures the efficient use of resources, leading to reduced costs and time during
both data collection and processing. Based on our findings, we recommend using the Faster mode with counted
super-resolution, binning 2, and non-gain normalized TIFF output file format for all strategies outlined below.
