<div dir="ltr"><div><div><div><div>Hi susumu;<br></div>I want to construct an atlas bundle from ICBM for use it in segmentation of SWM fiber bundles from tractography datasets using a priori information embedded in a fiber bundle atlas.<br>
Extract the fibers that traversed the ROIs,and re-assined the labeled ROIs of the template ICBM to a new atlas bundle<br></div>Can i do that with ROIeditor?<br></div>Thanks<br></div>AMIRA<br><div><div><div><br><br><br><br>

<div dir="ltr">Hi Amira,<div><br></div><div>I'm not quite sure what you are trying to do. If you superimpose the ICBM atlas on your patient data, various structures are defined in the patient.</div><div>Then do you want to use this information for tractography? In this case, you will use the defined brain structures (for example, the white matter beneath the motor cortex and the pons) to perform tractrograph (for example, the corticospinal tract).</div>
<div><br></div><div>In this operation, the defined structures by the ICBM atlas are used for seed ROIs for tractography and the actual process depends on the tractography tool you are using. Unfortunately, we don't have experience with DIPY or EUDX.</div>
