WebFeb 14, 2024 · The contrast transfer function (CTF) of tomograms was corrected using CTFplotter and CTFphaseflip tools from IMOD. To generate subtomograms of MTTs, A- and C-microtubules were picked along each MTT, generating nine sets of A-C paired coordinates along the centriole’s central region, always from proximal side to distal side. WebApparently relion_tomo_import_tomograms does not read the first line of a ctfplotter output (*.defocus). Adding a first line "#header\n" made it readable. 25 Dec 2024

WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebThe aligned tilt series were binned four times and reconstructed by weighted back projection in IMOD, resulting in the tomograms uncorrected for contrast transfer function (CTF) that were used for visual inspection of the quality of tomographic reconstruction, tubule picking, and defocus estimation using CTFPLOTTER (within the IMOD).
