PubMed has changed their display format recently. When user save the MEDLINE display page as plain text file, no white space is added between tag letters and the "-" sign. When user select and copy the text, one white space is added between tag letters and the "-" sign. This caused the old import fitler only work in one case. This new import fitler solved the problem by using regular expression. So it works for both cases. Please get the updated import filter at http://support.biblioscape.com/node/38. In Biblioscape, go to "File | Import Filters...". Click the "Import" button and select the download *.bif file and replace the old import filter when prompted. This updated import filter works for Biblioscape version 6 and 7.
