I think it should be useful if the text table import could be done via pasting (clipboard). I imagine a menu item Edit->Paste As..-> attributes table. I expect it is just a matter of parsing a stream of space or tab delimited chars... |

Proposal
This RFC is for the new import framework for general text files.
Biological Questions / Use Cases
Most of biological data files are available in text or Microsoft Excel file format. By implementing this function, users can import following files:
- Tab/comma/space delimited text tables
- Excel files
General Notes
Requirements
This project contains two main components:
- File readers
- for text files
- for Excel (xsl) files
- Swing GUI
To provide maximm flexibility for users, the GUI should accept the following:
- Selectable mapping keys. Users can map text
Deferred Items

The following is a prototype GUI for the file importer:

Features requested in the Hackason (first 2 days of Cytoscape retreat 2006) were the following:
Direct import from Excel files (.xsl) This can be done using open source library [http://jakarta.apache.org/poi/ POI].
- Support for multiple delimiters.
Network file import. This is related to [:SimpleTextTableImport:RFC 16 (text table network import)].
Inteligent file type checker. If the input file data looks like existing data file format, apply a template.
Backward Compatibility
Expected growth and plan for growth

Implementation Plan
Prototype readers and GUI is done.
