1. Raw image frames for the fungal retromer:Grd19 coat assembled on the Kex2 cargo-containing membranes
Category:
micrographs - multiframe
Image format:
TIFF
No. of images or tilt series:
82
Image size:
(3710, 3838)
Pixel type:
UNSIGNED 16 BIT INTEGER
Pixel spacing:
(1.379, 1.379)
Details:
Unaligned frames are not corrected for detector’s gain and defects. Ten frames were saved per each tilt image. The exposure dose per tilt image was 3.0 e/Å^2. Calibrated pixel size 1.379 Å. Movies are named as ts_[tilt stack ID]_[sequntial movie number]_[tilt angle].tif. For-gain reference and defect correction, use data/correction/CountRef.dm4 and data/correction/defects.txt

Defocus estimation was performed using IMOD ctfplotter on non-dose filtered aligned stacks (data/aligned_stacks).

2. Corrected, aligned and order-sorted tilt series for the membrane-reconstituted fungal retromer:Grd19 complex in the presence of cargo-signal containing C-portion of the Kex2 cargo.
Category:
tilt series
Image format:
MRC
No. of images or tilt series:
82
Image size:
(3710, 3838)
Pixel type:
UNSIGNED 16 BIT INTEGER
Pixel spacing:
(1.379, 1.379)
Details:
Corrected, aligned and order-sorted tilt series. The tilt-series were generated from raw frames (data/rawframes) by applying gain reference and defect corrections, motion correction and Fourier cropping to physical pixel size. No dose-filtering was applied.
