1. The new version has automatic outlier image slice rejection, based on the relative error >3%, I wonder whether there is document or paper illustrates this method, what relative error here refers?<br></div></blockquote>
<div><br>We are still testing several different types of outliever rejection methods. At this point, I recommend you to use the simple linear fitting option without the outlier rejection option (sorry, the default should not be the slice rejection option). It is, however, advisable to make sure that your data are free from corruption by carefully inspecting your data using the data inspection window. If you do find corruption, you can manually remove it (<a href="https://www.mristudio.org/wiki/user_manual/DTI_Studio_User_Manual/original_image_view">https://www.mristudio.org/wiki/user_manual/DTI_Studio_User_Manual/original_image_view</a>) or try one of the options for automated rejection. There are two types of automated rejection; slice rejection and pixel rejection. I hope that we can post the latest version with some documents this month. Meanwhile, if you are interested in, please try 2-4% of error threshold. If you didn't find any motion-related image corruption, there is no need to do the outlier rejection.<br>

2. The DWI data saved as NRRD, it is after outlier removal, correct? With any other processing? <br></div></blockquote><div><br>Do you mean your original DWI data are saved as NRRD (before imported to DtiStudio) or did you save your data in NRRD using DtiStudio? Why did you use NRRD? The outlier removal is a procedure for tensor calculation (it simply doesn't use some DWIs) and it does not touch the original DWI data.<br>

<br>
3. I am thinking to use the updated FA and DWI data from DTI studio to FSL FDT module, but do not know how to convert the .nrrd file or the .dat file into Analyze format. My colleage save in analyzed format in DTI studio, but it is not recognized both other programs. <br>
<br></div></blockquote><div><br>Hangyi, do you know anything about the compatibility issue of Analyze?<br><br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
