Dear Ahmed Tofayel

The latest em2em program handles all various FEI/EPU formats and 
converts it to all possible formats. The latest version that I have is 
from the 19th of June 2014 and I see the latest released version is from 
the 23rd of June (see: https://www.imagescience.de/download.html#em2em). 
I have used em2em successfully on all the various FEI formats. If you 
continue to have problems send your log-file to 
ralf.schmidt at imagescience.de and he will certainly help you! You may 
also want to convert your data first to the native imagic-4D stack 
format and from that to whatever format you want to work in. That has 
the added advantage that I also understand the error messages. (It of 
course remains possible that your files really are corrupted as 
suggested by XMIPP).

Hope this helps

I receive many emails per day and, although I try,
there is no guarantee that I will actually read each incoming email.
Moreover, our Spam filters can be strikt and sometimes make
legitimate emails disappear (try the gmail accounts, alternatively)
