25 Jan '06

Hi, I am trying convert the data from our 4T (Siemens) to mgz. But there is error message of "Floating exception": [antao@freesurfer fad131]$ mri_convert MR_16_100_2005_10_24_16_30_48_78125_49238781.IMA ../FAD131/mri/orig mri_convert MR_16_100_2005_10_24_16_30_48_78125_49238781.IMA ../FAD131/mri/orig reading from MR_16_100_2005_10_24_16_30_48_78125_49238781.IMA... Floating exception [antao@freesurfer fad131]$ Can someone help me solve this problem? Thanks, Antao

FW: [Freesurfer] overlay thickness maps

-----Original Message----- From: Kirk, Gregory Sent: Monday, January 23, 2006 4:25 PM To: 'Kevin Teich' Subject: RE: [Freesurfer] overlay thickness maps Yes Kevin, im still a dum dum sometimes, as your comment I Looked it in shell window, and saw all was not well. In response to Load-Overlay-> load lh.thickness from the subject surf/ Directory get errors % surfer: needs at least 2 marked vertices % surfer: needs at least 2 marked vertices % surfer: needs at least 2 marked vertices % mri_read(): couldn't determine type of file /home/gkirk/freesurfer-new/freesurfer/subjects/sickle_cell/THORNTONH/sur f/lh.thickness surfer: couldn't load /home/gkirk/freesurfer-new/freesurfer/subjects/sickle_cell/THORNTONH/sur f/lh.thickness sclv_read_from_volume: error in MRIreadInfo. The overlays that are loaded in the buckner are .mgz files and it does not seem happy with these Doug Greve is the winner in our best suggestion category with Another method is to use mri_surf2surf to to convert the curv file into an mgh file (run it with --help to see how to use it). Then just load the mgh file as an overlay (with "compute identity"). Which when applied with- and the output is- [gkirk@Nuit surf]$ mri_surf2surf --hemi lh --srcsubject MASONO --srcsurfval thickness --src_type curv --trgsubject MASONO --trgsurfval lh.thickness.mgz --trg_type mgz srcsubject = MASONO srcval = thickness srctype = curv trgsubject = MASONO trgval = lh.thickness.mgz trgtype = mgz surfreg = sphere.reg hemi = lh frame = 0 fwhm-in = 0 fwhm-out = 0 Reading source surface reg /home/gkirk/freesurfer-new/freesurfer/subjects/sickle_cell/MASONO/surf/l h.sphere.reg Loading source data Reading curvature file /home/gkirk/freesurfer-new/freesurfer/subjects/sickle_cell/MASONO/surf/l h.thickness INFO: trgsubject = srcsubject Saving target data Reshaping 2 (nvertices = 107662) Gives .mgz files that surfer is happy to use as an overlay, and produces what looks like good Thickness maps. Thanks all Greg. -----Original Message----- From: Kevin Teich [mailto:kteich@nmr.mgh.harvard.edu] Sent: Friday, December 23, 2005 5:33 PM To: Kirk, Gregory Cc: Freesurfer(a)nmr.mgh.harvard.edu Subject: Re: [Freesurfer] overlay thickness maps There are a couple things that could be wrong. Make sure that calculating an identity registration is the proper thing to be doing here. Doug can probably tell you more about this. Next, is the file actually loading? Make sure that the output to the shell doesn't have any errors, and that there's a new line in the label/value area with the overlay's name on it. Make sure that there are actually values in that line as you move the mouse aroudn over the surface. If there are, do View->Configure->Overlay and see if you can set the threshold so that it encompasses the values, as the default threshold might be incorrect.

notes on Jan 2006 release
by Sasha Wolosin 23 Jan '06

23 Jan '06

Dear all, In the notes on the Jan 2006 release it was mentioned that the subcortical atlas is built from the Siemens scans, and thus might not be reliable for GE scans. How might this subcortical atlas handle data aqcuired on a Philips scanner? thanks, Sasha Disclaimer: The materials in this e-mail are private and may contain Protected Health Information.

cannot configure overlay in tksurfer

23 Jan '06

Hi all, I'm trying to overlay some cortical thickness correlation maps onto a freesurfer surface, and when I select configure->overlay from the toolbar, an error message pops up stating: bad window path name ".wwConfigOverlayDisplayDlog.fwFlags.cbwReverse" bad window path name ".wwConfigOverlayDisplayDlog.fwFlags.cbwReverse" while executing "grid $cbwReverse -column 2 -row 1 -stick w" (procedure "DoConfigOverlayDisplayDlog" line 126) invoked from within "DoConfigOverlayDisplayDlog" invoked from within ".w.fwMenuBar.mbwView.mw.cmw5 invoke active" ("uplevel" body line 1) invoked from within "uplevel #0 [list $w invoke active]" (procedure "tk::MenuInvoke" line 47) invoked from within "tk::MenuInvoke .w.fwMenuBar.mbwView.mw.cmw5 1" (command bound to event) I'm using banzai and am working in the dev environment. If anyone can help me out, that would be great, thanks! -Eric

mri_convert ascii
by Sasha Wolosin 19 Jan '06

19 Jan '06

Dear all, Is there a way to convert FreeSurfer surface files to ASCII? In the most recent listserve, it was mentioned that mri_convert can be used to convert FreeSurfer surface files to ASCII format, but I could not figure it out- I thought mri_convert could only handle volumes.

Clustering methods for multiple comparisons
by Glenn Lawyer 18 Jan '06

18 Jan '06

Hi, Doug, You mentioned on the list that you are preparing a tool that uses clustering to reduce the multiple comparison penalty. Do you have time to post some more details, or perhaps just pass along some of your references? This area is very interesting to me. +glenn -- I want to go farther, farther! A. E.
