Reading dst and plt files

[wtam]

Dear Didier,

Would you mind sharing any scripts that read .dst and .plt binary files, as described on p.38 of the user's manual?

Best regards,
Wai-Ming

Dear Wai-Ming

I don't get script but 'C' code source, like following to write dst file.

Regards,

Didier

Code: Select all

char cc1=125,cc2=100;
FILE *f

f=fopen(dst_file,"wb");
fwrite(&cc1,sizeof(char),1,f);
fwrite(&cc2,sizeof(char),1,f);
fwrite(&nbr_part,sizeof(int),1,f); // number of particles
fwrite(&Ibeam,sizeof(double),1,f); // bema current (mA)
fwrite(&Freq,sizeof(double),1,f);  // Bunch frequency (MHz)
fwrite(&cc1,sizeof(char),1,f);

for (int i=0;i<nbr_part;i++) {
  fwrite(&Part[i].x,sizeof(double),1,f);  // (cm)
  fwrite(&Part[i].xp,sizeof(double),1,f); // (rad)
  fwrite(&Part[i].y,sizeof(double),1,f);  // (cm)
  fwrite(&Part[i].yp,sizeof(double),1,f); // (rad)
  fwrite(&Part[i].p,sizeof(double),1,f);  // (rad)
  fwrite(&Part[i].w,sizeof(double),1,f);  // MeV
}
fwrite(&Mo,sizeof(double),1,f); // particle mass (MeV)
fclose(f);

Dear Didier and Wai-Ming,
I have posted some MATLAB scripts for TraceWin to read .dat file on my webpage with following link,

I too have a script that can read .plt file. Please let me know if that's needed and I will be happy to help.

Dear Abhishek,

Thank a lot to share with us. But most of your links are password protected and moreover I don't see any concerning the reading of plt.

Regards,

Didier

Dear Didier,
My apologies for the inconvenience caused. Here I am attaching the Matlab scripts reading the .dst and .plt file in a .zip format. The scripts that are attached may require some variable changes like particle number or file name but the architecture remain the same.

Thank you

Dear Abhishek,

Thank you, I am sure it will be very useful for many.

Hi Didier,

On this topic, we have a script for reading the plt files in Python, but I was recently made aware that we are not able to read the files with compression. Looking in the manual I do not see how this compression is done. I was wondering therefore if you could provide a similar code snippet to show how you do it?

[Didier]

Dear Abhishek,

I have upgraded the documentation to explain the first 2 levels of compression (page 39), the third and last is not relevant.

Regards,

Didier

Dear Didier,
Thank you very much for updating the documentation. I am sure it will be very helpful for all TraceWin users.
