Image Sets

1. Unaligned raw multi-frame untilted micrographs of Influenza Hemagglutinin Trimer

Category:

micrographs - multiframe

Image format:

MRC

No. of images or tilt series:

447

Image size:

(3838, 3710)

Pixel type:

UNSIGNED 16 BIT INTEGER

Pixel spacing:

(1.31, 1.31)

Details:

Unaligned raw multi-frame untilted micrographs of Influenza Hemagglutinin Trimer. Micrographs were collected when tilt angle is set to zero. The gain normalization reference images (bright and norm) are included for each of the 3 sessions. No dark gain reference images are present because dark images values are always zero in counting mode camera.

Files:

Archives and downloads the selected files into an uncompressed zip file.

Depending on the number and size of files to be downloaded, this can take an enormous amount of time. Also, this feature is unstable and may not work properly, and checksums of downloaded files are not verified.

We recommend using rsync, aspera, globus, etc.

It is possible to download files by specifying the file list with rsync command, etc.

2. Aligned, summed and exposure weighted untilted micrographs of Influenza Hemagglutinin Trimer

Category:

micrographs - single frame

Image format:

MRC

No. of images or tilt series:

447

Image size:

(3838, 3710)

Pixel type:

32 BIT FLOAT

Pixel spacing:

(1.31, 1.31)

Details:

Aligned, summed and exposure weighted untilted micrographs of Influenza Hemagglutinin Trimer. Micrographs were aligned and summed from the raw frames using MotionCor2, with 5 by 5 patch and exposure weighting.

3. Equalized particle stack of Influenza Hemagglutinin Trimer

Category:

picked particles - multiframe - processed

Image format:

MRC

No. of images or tilt series:

130000

Image size:

(256, 256)

Pixel type:

32 BIT FLOAT

Pixel spacing:

(1.31, 1.31)

Details:

Equalized particle stack of Influenza Hemagglutinin Trimer. Particles were extracted from aligned, exposured weighted and summed micrographs. In order to compare these particles with a 40 degree tilted dataset, these particles were equalized based on GCTF-estimated per-particle CTF values so a subset of particles with the same defocus spread would be obtained. This equalized stack of 130,000 is the uploaded stack. A Relion .star metadata file is also provided containing the final refined Euler angles.
