[Chimera-users] Problem reading Delphi .phi into Chimera

[Boaz Shaanan]

Hi Tom,

I'll look for the source of the problem that you and Elaine pointed out. It may have to do with a newer Delphi version that I used to generate the file whereas previously I used an older version.

Thanks a lot for your help.

Hi Boaz,

  Elaine is right that the message means that the file looks either truncated or corrupted to Chimera.  A delphi file contains records with sizes of each record specified in the file and Chimera read the size of a record as 2 Gbytes, when the file itself was only 2 Mbytes long, so it said something is wrong with this file.

I.e., the file might be corrupted or truncated, or the values written at unexpected precision. Do you use any other programs that read phi files, and if so, can they read this file?
