Signature

Hi everyone. Im very new in EM so i want to apologyze if the question is a newbie one.
I have processed some micrographies and i want to make a image stack. The problem is that i cant append images to a stack because signature says that the images are too big. The images are 1000x1000 and i tried to bin the images to 500x500. This works but i miss too much info. Any idea?
Thanks.

Hello,

We installed signature in our machines and seem to be working fine.
The only problem is that we do not seem to have anywhere the Particle Alignment option under the Function Menu. We also don't have the option to upload the map density. These things are mentioned in the manual and tutorials but they do not appear in our version of the software.

We installed the linux64 patched version.

Any ideas?

Thank you very much!

Hello,

I have been trying to install the patched version of Signature on 32-bit Linux and on iMac. Unfortunately without success. If seems that the compilation fails. Does anyone know how to overcome this issue or has the patched version for 32-bit Linux that I could download?

Many thanks in advance

Does the Windows XP version of the Signature software program run on Windows 7 or is there a version of Signature that is compatible with Windows 7?

Thanks,

Hi everyone,

I'm trying to use Signature to select the particles from my micrograph, given a template.
I would like to get coordinates the picked particle and angle respect to the template to calculate nearest neighbor distance and angle distribution. After importing, I find that both micrograph and template are rotated by counterclockwise 90 degree and mirror-imaged across the mirror plane lying along y = x of the rotated image.

Hi. Is it possible to generate .prj files for Signature in a more automatical way? For instance, is it possible to write a script (in phython/fortran.. etc.) to generate .prj files and then be used for batch processing?
Thanks.

Dear all,

Which version of Signature supports template extraction? In the tutorial below the GUI has expanded functionality that the Linux 64 binary does not seem to have. Can anyone point me in the right direction?

Hi,
I am new here and first want to thank you for making available this fantastic software! Since I do not want to invent the wheel again: Does anybody have a script that converts the .plt (or any of the other) coordinate file output by signature into the .bcrd format used by auto3dem? As we also use xmipp, same question: script for conversion into the format used by xmipp?
Thanks a lot, Dieter
