Emap2sec

Emap2sec is a computational tool that can identify protein secondary structures in cryo-Electron Microscopy (EM) maps of medium to low resolution.

Input file:
    EM map file (mrc format file).
Parameter:
    Contour Level.   Please make sure your contour level is lower than your focused region. This is the absolute density threshold, not the standard deviation.

Result Visualization Panel:
The purple, yellow, and green spheres respectively represent the alpha helix, beta strands, and coil.

Output Logs Panel:
The "Output Logs" panel include all the outputs from the scripts. If you are interested in the progress of the job during running, you can take a look at it.

Job Configuration Panel:
The "Job Configuration" panel includes the input parameters for this job, which is used to keep the records of your submitted input.

Problem Debugging:
If you encounter any problems, feel free to email us to report the problems. In your email, please use subject as "Emap2sec+ problem: [jobid]", here [jobid] is the job is shown in the title. We will use the jobid to locate and debug jobs in the backend and get back to you as soon as possible.

Please make sure your contour level is lower than your focused region. This is absolute density threshold, not standard deviation.

Please input valid contour level since it is used for normalization in Emap2sec. 0 is not suggested and may ruin the visualization..
