[3dem] Re: file conversion (aaron smith)

[Shi PhD, Dan]

Hi Bob,
Thanks for your message and information,
To now, we know there are several packages can convert emi or ser format
to popular Cryoem formats with or without specific instruction. But I
don't know if Tia save one image to two files is normal.
If FEI is willing to improve Tia, the issue would be solved at the root
for all of Tia users. If modifying Tia is a major upgrade or too difficult
to its software develop team, we have to do whatever to process the data
with extra steps.
We all appreciate the groups who have devoted their time and effort to
develop the converting software,
Kind regards,

Dan
