Image Sets

1. Unaligned multi-frame micrographs of ArnC from S. enterica in the apo state collected on Talos Arctica

Category:

micrographs - multiframe

Image format:

TIFF

No. of images or tilt series:

5552

Image size:

(3838, 3710)

Pixel type:

UNSIGNED 32 BIT INTEGER

Pixel spacing:

(1.038, 1.038)

Details:

The dataset contains unaligned gain-corrected micrograph movies in TIFF format. Cryo-EM data were collected at the Rutgers Cryo-EM & Nanoimaging Facility using a 200 kV Talos Arctica (FEI/ThermoFisher) electron microscope equipped with a K2 Summit direct electron detector (Gatan) and a BioQuantum energy filter (Gatan) with slit width of 20 eV. Data were collected automatically in counting mode using EPU (FEI/ThermoFisher), a nominal magnification of 130,000X, a nominal pixel size of 1.038 Å/pixel, and a dose rate of 5.420 electrons/pixel/s. Movies were recorded at 200 ms/frame for 7s (35 frames total), resulting in a total radiation dose of 35.21 electrons/Å2. Nominal defocus range was -0.5 to -2.5 μm. A total of 5,552 micrographs were recorded from one grid over three days. Micrographs were gain-normalized and defect corrected. At the end of processing a calibrated pixel size of 1.05 Å/pixel was determined for this dataset, representing an 1.16% error from the nominal pixel size value.
