Dear ImageJ community
I have problems with image files generated with the Olympus proprietary software "CellR". I would like to know if there is a way to open apl files from ImageJ and also to open the tif files generated by CellR without trasnforming them into the 8-bit format. Thank you very much in advance Sincerely Marialuisa Malosio Maria Luisa Malosio, PhD Diabetes Research Institute Cell Imaging Unit L25, 1°piano, Settore Q Fondazione Centro San Raffaele del Monte Tabor Via Olgettina 60 20132 Milano Italy Phone:+39 02 2643 3184 or 2913 Fax: +39 02 2643 2914 Cell 3471656237 |
Hi Maria,
Bio-Formats (http://www.loci.wisc.edu/ome/formats-imagej.html) has preliminary support for the Olympus CellR/APL format. Give it a try and let us know if you run into any trouble. We'd also be interested in hearing whether it works with the TIFF files from CellR (no reason it shouldn't).

Dear Curtis,
Many thanks for your suggestion. I have added the Loci_tools plugin to ImageJ. I have tried to open an uncompressed tiff file generated by CellR using the Bio-format importer, is this correct? I was able to open it and the two channels of the acquisition were visible in tow separate windows, though with different false colors than originally. I have also tried to measure the signal intensity of some ROIs, that I had already analyzed with CellR. The problem I see at the moment are the numbers that I obtain from these measurements, they are quite different from those that I obtained within CellR. The range of CellR is 1000-1300 for an average ROI, in ImageJ I obtain values of 17000-35000 for the same type of ROIs. Also the background value is higher than a ROI around a signal. This is scary!!! Don't you think so? I don't know exactly what to do in order to trust the analysis on the original files opened in ImageJ. Thanks for any imput.

Dear Marialuisa,
the numbers you get are less scary if you take the different bit-depth into account. If you have a 12-bit camera on your system everything is more or less fine. For the 12-bit image you get 1000/4096=0.24 equals 24% of dynamic range. As ImageJ is not supporting 12-bit everything is converted to 16-bit. If you do the same calculation as above you get: 17000/65536=0.26. Thus the values are more or less identical if you take the dynamic range into account.

I don't think so ImageJ opens 12 bits images as 16bits, but it does NOT change intensity values. a 12bits image in imageJ will be a 16bits image with no value higher than 4095 (the max for 12bits). When you are saving your 16bits tiff files in cellR, maybe you are choosing an option where cellR stretch the intensity values over the full 16bit range (0-65k) so it looks good in Photoshop? If not, it could be an issue with bio-formats. -- Mathieu Marchand -- Bio-Imaging Resource Center, The Rockefeller University 1230 York Avenue, box 209, New York, NY 10021 http://www.rockefeller.edu/bioimaging . +1-212-327-7487 (7489 for fax) > Dear Marialuisa, > > the numbers you get are less scary if you take the different bit-depth into > account.

Hi Marialuisa,
Many thanks for your suggestion. > I have added the Loci_tools plugin to ImageJ. > I have tried to open an uncompressed tiff file generated by CellR using > the Bio-format importer, is this correct? With Bio-Formats, you can open either the original APL file or the exported uncompressed TIFF. Use whichever one is easier for you. If you notice problems with either approach, please let us know, as we are committed to fixing any bugs in the Bio-Formats library. I was able to open it and the two > channels of the acquisition were visible in tow separate windows, though > with different false colors than originally.

Would you be able to send us both the original APL, and corresponding exported TIFF, for one of your datasets? It would be very helpful for investigating the problem, and we would use the data only for internal development purposes. Files under 15 MB can be sent as email attachments; if you need somewhere to store larger files, let me know and I will send you our FTP server information off-list.
