<br></div> For example, with the code in the state you sent me, PixelType is an unsigned short (which is 16 bits) and the dimension is 3.<br><br></div> These settings would be incorrect for the 2chZT.lsm sample data, as it has an 8 bit unsigned pixel type (so PixelType should be defined as unsigned char). Also if you're using the SCIFIOImageIO you can typically set dimensions to 5.<br>
<br></div> I don't know the specifications of your .oif dataset, but the PixelType and dimensions may need to be adjusted for it.<br><br></div> Sorry if you already knew this and were updating these values!<br><br></div>
Anyway, I've been working on improving the stability of the SCIFIOImageIO plugin. Using the itkSCIFIOImageIOTest I mentioned previously, I confirmed that I was able to read and write the 2chsZT.lsm file and the .oif test images I have access to.<br>

This patch adds a true Bio-Formats (SCIFIO) ITK ImageIO, which will be available by default in ITK.<br>
<br></div> This means that the old bf-itk-pipes plugin won't be supported, as all development efforts are going towards the SCIFIOImageIO.<br><br></div> As this code is still under review, there are issues that I'm currently working on resolving.<br>
<br></div> So first I'd ask that you check out the latest patch code using the links on that review site and rework the splitting code to use <a href="http://review.source.kitware.com/#/c/9450/3/Modules/IO/SCIFIO/include/itkSCIFIOImageIO.h" target="_blank">SCIFIOImageIO</a> instead of the BioFormatsImageIO.

<br></div> If the latest SCIFIOImageIO still gives you problems with your .oif dataset though let me know and I'll investigate.<br><br></div> As for the 2chZT data, that sounds unrelated to the hanging so I'll take a look at it locally when I get a chance.<br>

<br> From what I can tell there are two separate issues preventing your code from writing the desired regions.<br><br> First of all, the IORegion needs to be set on the Writer, for example:<br><pre><div>
<span>writer</span><span>-></span><span>SetImageIO</span><span>(</span><span>io</span><span>);</span></div><div> <span>writer</span><span>-></span><span>SetInput</span><span>(</span><span>reader</span><span>-></span><span>GetOutput</span><span>());</span></div>
<div> <span>writer</span><span>-></span><span>SetIORegion</span><span>(</span><span>region</span><span>);<br> writer->Write();<br>
</span></div></pre> In the original code you sent to me, that wasn't happening and it was defaulting to the first 3D region and thus the first time point. I mentioned this, without providing a code example, in a past e-mail - so apologies if you've already updated your code!<br>
<br> Note that according to the <a href="http://www.itk.org/Doxygen/html/classitk_1_1ImageFileWriter.html#ab2cba65f716aa75ec962171ee0b46fe3" target="_blank">itkImageFileWriter API</a> Write() is a special form of Update() that respects the IORegion. However, in practice, for me it still just writes the largest possible region instead of what was specified. So that could suggest a bug in the bf-itk-pipes plug-in.<br>
<br> The second issue is that even after manually specifying the IO regions, the Reader output still has the largest possible dimensions (T=2) so the current gist test ends up creating 2 full copies of the image. I think this was always happening at the Reader, but then it was truncated to the first time point you saw by the Writer. Anyway, this implies that the full image is still being read, despite the region specifications.<br>
<br> I think this is a side effect of setting using the LargestPossibleRegion in the Update() method, as mentioned in the <a href="http://www.itk.org/Doxygen/html/classitk_1_1ProcessObject.html#a4041fb21e9105500eee311e265691bd5" target="_blank">itkProcessObject specification</a>.<br>
<br> Right now I'm going through the examples from <a href="http://itk-insight-users.2283740.n2.nabble.com/Memory-limits-of-ITKImage-object-td5670422.html" target="_blank">this ITK Users thread</a> about streaming for a better pipelining solution. I'm also testing to see what can be done at the ImageIO level, as when Read and Write are hit in the itkBioFormatsImageIO, GetIORegion() is already returning the largest possible region, instead of the specified region.<br>
<br> I'll keep you updated.<span><font color="#888888"><br><br>- Mark</font></span><div><div><br><br><div class="gmail_quote">On Tue, Oct 16, 2012 at 1:37 PM, Kishore Mosaliganti <span dir="ltr"><<a href="mailto:kishoreraom@gmail.com" target="_blank">kishoreraom@gmail.com</a>></span> wrote:<br>

<div><div>Dear Mark,<br><br>Thanks for the clarification. My original problem remains unresolved. For example, in the LSM gist on lines 104-107:</div><div><br><div><pre><div> <span>ReaderType</span><span>::</span><span>Pointer</span> <span>reader</span> <span>=</span> <span>ReaderType</span><span>::</span><span>New</span><span>();</span></div>

<span>reader</span><span>-></span><span>Update</span><span>();</span></div></pre><br></div></div><div>Here,
calling reader->Update() loads the entire image into memory. If you
have a very large LSM file (several gigabytes large), then this code
will fail since such an image cannot get into the memory. <br>
<br>Hence, I am trying to send the read region directly into the reader using<br><br>io->SetRegion(region);<br><br>and then <br><br>reader->SetImageIO(io);<br>reader->Update();<br><br><br></div>But this step is not giving me two different timepoints. It is writing out the same timepoint.<br>

<a href="https://gist.github.com/3900888" target="_blank">https://gist.github.com/3900888</a><br>
<br> That example is currently working for me, in that it writes out 2 images of 72 planes - one for T=0 and one for T=1. Since everything in ITK seems to be pipeline-oriented, I am not sure there is a solution to splitting out channels just using Setters like we were both trying.<br>
<br> Instead, I followed <a href="http://www.vtk.org/Wiki/ITK/Examples/ImageProcessing/RegionOfInterestImageFilter" target="_blank">this ROI Filter example</a> and used the logic from my last e-mail.<br><br> I do need to correct one thing I said in my last e-mail: SizeT should always be 1, as it is a relative offset to the Index value.<br>
<br> When I ran that test, both images went to grayscale.. I'm going to see if that's an error in the bf-itk-pipes logic, or just something that needs to be set up differently in using the ITK API.<br><br> Let me know if you run into any more problems with this code, or if you just want to discuss any part of it.<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Kishore,<br><br> I am sorry I wasn't able to get to your issue yesterday. Looking at it today, I think there are a couple of things going on here.<br>
<br> First of all: in your test class<br>- I consolidated a BioFormatsImageIO and the ImageIOBase.<br>
- In the region updating loop, the wrong region (dim-3 instead of dim-2) was being set, and only the index is set. I suspect both the index and size need to be set.<br><br> I attached an updated version of your test, where in the first iteration it sets IndexT = 0, sizeT = 1. The second iteration sets IndexT = 1, sizeT = 2. I believe those regions will split the time points as you wanted.<br>
<br>But there is a second issue: although the Reader IORegion is correct (I think) the Writer is not. It is defaulting to the ITK base 3D region. When I tried setting the Writer's region to our desired region, it throws an exception because the 5D region can't be contained by what it thinks is the largest possible (3D) region. I am refreshing myself on the ITK API and once we figure out how to set that region, I think it will write the images correctly (or we can move on to the next problem).<br>
<br>In your test I changed the output format to ome.tiff because I know that will use the itkBioFormatsImageIO writer code, which I know is capable of handling 5D writing.<br><br>Also, in testing I found a couple of bugs in the ITKPipesBridge code. I started a new branch to fix these and any other issues that may be discovered. If you want to use the itkBioFormatsImageIO writer code you'll have to use this new branch for now. You can find it here:<br>

Otherwise, I'll let you know as soon as I have the Writer region setting properly.<br>

Hi Kishore,<br><br> I helped develop the bf-itk-pipe plugin and am investigating your issue right now. <br><br> What you're doing seems reasonable, so I'm trying to determine if there's a bug in the plugin. My goal is to have some working example code for you (and a fix if necessary) by the end of the day.<br>
<br>Thank you for using our plugin!

<br>Instead, the itkImageFileReader seems to be extracting the same image region although I update the requested region in the BioformatsImageIO class :;<br>
<br> itk::BioFormatsImageIO::Pointer io = itk::BioFormatsImageIO::New();<br> io->SetIORegion( region ); // doesn't make a difference in terms of image data extracted. Its always from the beginning.<br><br> ReaderType::Pointer reader = ReaderType::New();<br>
reader->SetFileName(argv[1]);<br> reader->SetImageIO(io);<br> reader->Update();<br><br>So, my general question is whether the BioformatsImageIO expects the whole LSM image to be loaded into memory before writing it out? I would like to specify small image regions since my LSM is too large to be fully loaded into memory. How else can I stream data from large LSM?<br>
