introduce more Mac-friendly installation process (simple drag & drop app to the desired location) and
remove the administrative privileges requirement for single-user installation
Fixes to Known Issues
Issue: Data migration of molecules with no Author name.
Resolution: For molecules with no Author name, the name would be set as ‘UNKNOWN’
Issue: Data migration of molecules and subset with spaces in their names
Resolution: The space in the name of subsets and molecules is now read and saved as it is. In previous
versions, the space was getting replaced with a “\”
Issue: Data migration will create a blank and invalid Vector NTI Express database at default database
location when started before Vector NTI Express is started
Resolution: Data migration won’t create a blank and invalid Vector NTI Express database when started
Issue: Data Migration will crash when “Start Migration” and “Cancel” clicked repeatedly
Resolution: Data migration will not crash when “Start Migration” and “Cancel” clicked repeatedly
Issue: Unable to import files from because the internal name is the same on multiple molecules
Resolution: Internal name being checked during importing, option to allow user to rename file or overwrite
existing data in the Database Explorer
Issue: Unable to rename data in Database Explorer
Resolution: User will be able to rename data with ‘UNKNOWN’Author name. After renaming, the Author
name will be replaced with user registered name
Known Issues in Version 1.2.0
Issue: Migrated analysis results will be displayed as “Foreign” under Local/Foreign column
Workaround: N/A
Issue: When hovering over Methylase enzymes (subset of 6 Methylase Enzymes) that cuts sequences
before recognition site, the “red” line indicating the cut sites are 1 base off. However, the indicated
sequences are correct
Workaround: N/A
Issue: Author Name will not be displayed in Molecule Editor properties pane when the migrated data
Author information are in the following conditions:
- Original Author name exists while Author name does not exists in the file
- Both Original Author and Author do not exist in the file
Workaround: N/A
Release Notes for Vector NTI Express Designer Version
1.1.1
Fixes to Known Issues
Issue: Contig Express – Occasionally, contig with chromatogram is truncated at both ends of the page
width after printing alignment with chromatogram.
Resolution: User can print contig alignment with chromatogram without truncation at both ends of page
width
Issue: Contig Express – Printing alignment with chromatogram is slow when printing is performed in Mac
OSX.
Resolution: Performance of printing alignment with chromatogram is tuned
Release Notes for Vector NTI Express Designer Version
1.1.0
What’s New and Improved in Version 1.1.0
Contig Express
ContigExpress is a program for assembling and editing sequencing fragments, either in the form of text
sequences or chromatograms from automated sequencers, into longer contiguous sequences or “contigs.”
ContigExpress uses CAP3 to drive the assembly process. This widely-used sequence assembly program can
use quality value scores (QVs) in ends trimming, contig construction and consensus calculation. It also
produces excellent results when QVs are unavailable. It is capable of using forward-reverse constraints to
evaluate contigs, a feature that helps in accurate placement of repetitive sequence fragments. It can also
identify and discard chimeric sequencing reads that frequently result from lane tracking errors. One of the
major strengths of CAP3 is its consensus generation algorithm based on weighted sum of QVs.
ContigExpress analysis can be saved as a ContigExpress Project, which contains the fragments, their
assemblies, and assembly options. In ContigExpress, fragments can be edited directly, with the
chromatograms in full view. Changes are tracked and a history is maintained. The contigs generated can be
saved to theVector NTI® Express database.
Fixes to Known Issues
Issue: Display Profile - Feature Label that is edited in the Graphic edit mode will revert to the original label
display when the molecule is opened as a Molecule Document file.
Resolution: User can edit feature label in Graphic edit mode and the label can be saved and displayed
when the molecule is opened as a Molecule Document file.
Known Issues in Version 1.1.0
Issue: After doing multiple editing on the sequence, the color indication shows incorrect combinations for
matching sequences.
Workaround: Include a patch in future
Issue: Application can support saving a Contig Assembly Project with up to approximately 400 without
chromatogram fragments with 42 contigs (Each fragment size is approximately 1000bp). Saving large
Contig Assembly Project will cause out of memory issue.
Workaround: User can choose to discard Chromatogram when importing fragments into Contig Project to
avoid Out of memory issue.
Issue: Application can support running ORF for approximately 3 times for large Contig Assembly Project
with approximately 200 fragments with 20 contigs. There is out of memory issue upon running a few times
of ORF in a large contig.
Workaround: Include a patch in future
Issue: Fragments are not aligned properly when a CEP file that was previously edited by user (at the
sequence level) is imported.
Workaround: Include a patch in future
Issue: Performance - Application takes several minutes to print aligned Chromatogram to PDF in Mac OS.
Workaround: Include a patch in future
Issue: Software does not update the database when attempting to re-save an imported VA contig project
that contain contigs in forward direction
Workaround: User can choose “Open” instead of “Import” to open the Vector Advance .cep project then
do a 'Save” after editing and subsequently the save to database will work
Issue: Fragment ends trimming - trimming does not take in edited fragment sequence
Workaround: Include a patch in future
