I'm having the same issue as Nancy, above. With the anatomical as the source image and the mean EPI as reference, these two files align, but the files listed under 'other' are not realigning and going forward to later stages of processing, the activation is then outside the glass brain once I arrive at the higher level analyses. Any idea why this might be happening?

However, the rest of the EPIs from the realignment stage that I enter in as "other" images to coregister are not ending up in the same space. Visually, shouldn't they be? These are the images I will carry onto further stages of analysis, so I just want to see if something is going wrong.. Thanks!

I have a dataset with 6 runs, which leads to high computational demands and long processing times if each run has to be coregistered an normalized separately. Is there a more efficient way to deal with this?<br /><br />Thank you very much,<br /><br />SebastianSebastian Peternoreply@blogger.comtag:blogger.com,1999:blog-1405968300258104460.post-73079952418356187742016-02-14T12:24:13.836-05:002016-02-14T12:24:13.836-05:00I'm very glad to hear that the videos have hel...I'm very glad to hear that the videos have helped! And yes, you're right about what corresponds to what; I did get those switched around. Although, technically, you could make either one the reference and the other the source (but if you're getting ginormous output, you should probably stick to the other way).<br /><br />Best,<br /><br />-AndyAndrew Jahnhttps://www.blogger.com/profile/16435706598096921650noreply@blogger.comtag:blogger.com,1999:blog-1405968300258104460.post-42590273480794444642016-02-11T11:09:21.388-05:002016-02-11T11:09:21.388-05:00Hi Andy, love the videos!

In the vi...Hi Andy, love the videos! Tiny mistake? <br />In the video you supply the average EPI as a reference image and anatomical as the source; In the paragraph right above the video you write the instructions the other way around:<br />"Usually the average EPI image - output from the realignment step - will be used as the source image, while the anatomical image will be used as the reference image".<br />I believe that reference should indeed be average EPI and the source - anatomical, because I came here for a quick refresher, only looked at the text and now my functional files are 4gb a pop :/<br /><br />Thanks for making the videos, they got me all through my master's degree and now I'd still be lost without them in my PhD.<br /><br /><br />Anonymoushttps://www.blogger.com/profile/12126060361588083417noreply@blogger.com
