Working with FTV Files |
|||||
FTV Interface ElementsData downloaded from a Finch Server are stored in an XML formatted file (FTV) that contains an ".ftv" extension. When FinchTV reads these files a number of new options become available to the application. The Finch menu becomes active, version information is displayed and vector containing and low quality regions (if they exist) become highlighted. Additionally, printing or FASTA export options that highlight vector and low quality regions, or mask these regions in exported sequences, obtain their information from the FTV file. Editing DataWhen edits are made to sequence data, and before they are saved to the Finch Server, the Version Number will display a tilde (~) to show that edits have not been saved. FTV files support all of the standard editing operations with the following differences: The Revert to Saved feature is unavailable. Changing a base to an "X," highlights the base as vector. At anytime, edits can be committed to the Finch Server by either clicking the Commit Edit Button, selecting Finch > Commit Edits from the menu, or typing ctrl E (Win) or cmd E (Mac). When a commit edit action is performed, the Read Edits Comment dialog is presented. Type a comment and click OK to save edits back to the Finch Server. The status bar will indicate a successful commit.
A revision history of edits can be later reviewed in the Chromatogram Revision History page for a read in the Finch Server. There are two cases where you cannot save edits back to a Finch Server: The Finch Server is not licensed for storing edited data, or you do not have permissions to save edits on the Finch Server. Saving FilesFinchTV can also be used to export data to the local file system. These data include DNA sequences in FASTA format and chromatograms in SCF format (saving data in AB1 files is unavailable with FTV data). To save edits into an SCF formatted chromat, select File > Save As from the menu. When data are saved in SCF format, information about vector and low quality regions are lost. |
