Exporting the list of Good Images

Hi Tim,

After Find CTF, I examined the images and the CTF Fit, and selected a set of 'good' images.

Is there a way to export the list of these good images that I have slected.

I would like to also try processing in Relion, but do not want to go through all the images again to select the good ones.

Thanks,

Stephen

Hi Stephen,

You can do this by directly accessing the database. This is one of the examples covered in the "images in a group" section here :-

https://cistem.org/documentation#tab-1-16

Hi Priyanka,

Is this from Relion 3.1? If so then it won't work as 3.1 is not supported in the released version of cisTEM.

There is some discussion here :-

https://cistem.org/cant-import-relion-31-particles-cistem

You can modify the star file so that it will import, you essentially have to convert it into the old style.

Thanks,

Tim

regarding alignment of movie file

Can someone please suggest me regarding an issue with movie alignment.I have encountered a difference between the motion corrected micrograph when I am doing alignment of movies in Relion and cisTEM.I have seen that when I am doing motion correction as well as ctf correction both in cisTEM then resolution fit curve is different as compared to when I am using motion corrected micrographs by Relion then doing ctf correction in cisTEM.I know in both the software the algorithm is different so can someone tell me which way I should follow.

It would be really help in data processing.

Thanks

Priyanka

Hi Priyanka,

The alignments will be different, also in cisTEM the default is to use the movies for CTF estimation, if you import images from Relion then it cannot use Movies.

Thanks,

Tim

Hi Priyanka,

What error are you seeing?

Hi Tim

This is the error

home/grigoriefflab/compiled/wxWidgets3_static/include/wx-3.0/wx/strvararg.h(456): assert "(argtype & (wxFormatStringSpecifier<T>::value)) == argtype" failed in wxArgNormalizer(): format specifier doesn't match argument type.

Please suggest me how to tackle it

Hi Tim

the alignment wouls be different but in CTF estimation it can take images also.So we can use Relion motioncorrected images.

regarding retracing the particles selected from 2d classes

Can someone suggest me how to retrace the particle position selected after 2d classification.I want to see the selected particles on micrograph itself from which particle belongs to.

Thankyou

Hi Priyanka,

This looks like a star file for images, not a particle stack. Am I correct. cisTEM will only directly import a particle stack and corresponding star file.

Hi Priyanka,

Do you have all your particles in a single file, or do you have a different file for the particles from each image?

significance of Alias resolution

Hi,

Can someone please comment on the significance of Alias Resolution parameter shown during CTF estimation.If it is showing NONE then what does that mean?

Is there any relation of this value with Fit resolution?

Thanks,

This is the resolution that

This is the resolution that the CTF starts to osicallate every pixel - if it is none it means that does not happen within your resolution range.

In general, this is not something you probably have to worry about.
