<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">The truth is (for Germany) that most scanners sold are still for isolated research projects. Digital pathology as a “complete digitalization” of a diagnostic pathology institute is not
yet happening. However, the “game” is slowly starting now and there will be pressure coming from the doctors as soon as they want to interact with colleagues hitting a brick wall of vendor formats.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">I know that some of the vendors already have a hard time selling their scanners due to bad (non-open) formats.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">There are some great developments though (not yet marketing). One engineer husband of a dermatopathologist now builds his own scanners with a Kuka robot arm in between loading them.
When I first saw this, I could not speak for 10 minutes – it really was like this first iphone moment.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">After having scruitinized all available scanners on the market he quickly saw that NONE of them was ready for digitalizing 1,000 slides per day. Most scanner vendors do the same mistake:
all 1,000 slides queue in front of only one objective. Or you buy 3 scanners (a 250,000€) to speed up the process, which no pathologist will ever invest due to lack of return of investment. Thus, he took his wife’s fate into his own hand and started constructing
scanners. I really hope his small company will succeed.<o:p></o:p></span></p>

<p><span lang="DE">I don't work with C interface, I just use the tools under Linux and recently have problem with the Mirax files generated by the new 3DHistech scanner. The new file format does contain some extra information that OpenSlide rejects or doesn't
understand. I read in other mailing lists that people have successfully use 3DHistech converter (free download from 3DHistech site) to convert from MIRAX format to MIRAX format (same format conversion) and can successfully use the converted file with OpenSlide.
The converter basically removes the extra overlapping information from the file, This is an extra step that needs to be done on the scanner PC. Is there possibility that OpenSlide library can be updated to avoid this conversion step, eg, skipping the overlapping
information in the new Mirax format.<o:p></o:p></span></p>

some error, however, calling openslide_get_error immediately after just returns a null error object.

get it working but had no idea what they changed to get it to work. So I am looking for some suggestions on what to try. I have tried retrieving all the data for the entire level 0 using a tile size of 512x512 and they all seem to come back with 0's. I
tried getting an entire higher level (level 6) with one call but same result. I have also tried various different Mirax slides (including some of the demo ones from the OpenSlide site) The code is pretty simple:<o:p></o:p></span></p>
