Request from user:
"I noticed a serious bug with processing VectorNTI files: after the manupulation with DNA sequence the Ugene saves the modified .gb file with COMMENT field in inverted order. The modifed file can be opened and processed normally by Ugene, but not VectorNTI. VectorNTI gives message "Failed to read serialized VNTI data". You can compare attached files (with Notepad or other texteditor). I have written a Python script that makes COMMENT field normal, file processed with this script is normally used by both Ugene and VectorNTI.
I guess Ugene makes no changes in the COMMENT field but just write the lines in opposite order."
