Our Olympus CellR system generates “Big Tiff”-files (.btf) instead of conventional Tiff-files if a multidimensional acquisition experiment exceeds 4GB. Bitplane’s Imaris does not recognize the btf. ImageJ tries to open but freezes... Does anyone know which programs can open and handle these files?

Hi Oliver,
If you are using 32-bit version of ImageJ that may not be able to load files larger than 4 GB. 64-bit ImageJ should be able to do so. I think when RAM is low, one can use virtual stacks to load only those slices that are being processed. LOCI bioformats supports files from CellR but no mention of big-tiffs. http://www.loci.wisc.edu/bio-formats-format/olympus-cellrapl A post here suggests that big tiffs are supported: http://n2.nabble.com/Opening-btf-files-td4074793.html hope this helps Shalin On Mon, Nov 30, 2009 at 7:42 PM, Oliver Biehlmaier <[hidden email]> wrote: > Hi everyone, > > Our Olympus CellR system generates “Big Tiff”-files (.btf) instead of > conventional Tiff-files if a multidimensional acquisition experiment exceeds > 4GB. > Bitplane’s Imaris does not recognize the btf.

I'm not sue, but perhaps the Aperio ImageScope viewer or the Olympus/Hamamatsu Nanozoomer viewer (NDPview) will do that.... I believe both instruments acquire data in big tiff format; both viewers are downloadable, so it should be easy to try them out and see...

Hi Oliver
I have had similar issues with Bigtiff files from Olympus CellR. I posted to the ImageJ list last week and Curtis Rueden (OME Loci) is having a look at why I can't open them using the Bioformats plugin. My solution at present is to use the CellR software to split the file in to a tif image sequence and load the sequence in ImageJ (64bit Java in Linux with 6Gb RAM allocated). Imaris should also be able to import the sequence (on a 64bit computer with plenty of RAM) but you will have to check the channel, Z and T dimensions after import .
