When exporting to PRIDE XML format:

• PRIDE messages having ERROR severity are displayed in the hEIDI console
• ALL PRIDE messages (DEBUG, INFO, ERROR…) are displayed in a separated file (pride.log) at the hEIDI root

It's very important to have a look to this log file, especially to check:

• Database name may be too long and truncated to 30 chars. Check it is still meaning full.
• “Home made” peptide modifications don't have UNIMOD definition. Check them !
• …

When PRIDE XML export is finished, a dialog will popup to display the log file. You can recall this PRIDE log using:

• View→PRIDE log menu from hEIDI
• Go to the Windows Explorer and open the <HEIDI_INSTALL_DIR>\pride.log folder in your favourite text editor
