>>We have a Neurolucida system and a Leica 4D confocal. Now I want to use the >>serial sequence of images obtained through the confocal microscopy to trace >>the neuron by the Neurolucida system. The problem is that the image format >>for Neurolucida is BMP and the confocal image format is TIFF, how can I >>use the confocal images by the Neurolucid? If someone has the experience >>about this, please give me the information. Thank you for your attention. In addition to the helpful suggestions offered by Chris Pudney, you may wish to check out my software pages for links to some packages that can convert between formats: http://www.cs.ubc.ca/spider/ladic/software.html If you have access to a Unix workstation, then Chris' suggestions are good ones. Here are my picks for image conversion (including PC and Mac platforms): Unix: ImageMagick PC (Windows): PaintShop Pro PC (DOS): Display Mac: Graphics Converter What's nice about all of these is that they can handle batch conversion.
