just make sure that the window shows as you want it (you may need to redraw it before hitting save). On Wed, 12 Jul 2006, Chacko Cherian wrote: when i want to print-out the outputs using "Save TIFF as" it isn't giving me any results.Is there something else that I need to do to save the output

we are currently limited to 256^3, which fits pretty much every brain I've ever seen. What is 310^3? This is on our to-do list. Bruce On Thu, 13 Jul 2006, Abdel Douiri wrote: Hi all, I want to try Freesurfer in object with a physical sizes are (310.00 mm, 310.00 mm, 310.00 mm) but I ha

Hi Darren, I just found out that when you save a label in tksurfer, it saves it using the orig surface coords, which explains the discrepancy. Try running label2label with --trgsurf orig. Alternatively, you can save your label in the white surface if you start up tksurfer with -orig white do

Hmmm, I just tried this and did not have a problem. There's something funny going on here. The indices for both labels are the same, only the cooridnates are different. This means that the source label and the new label are using different surfaces. Are you sure you created the source label fr

Hi Doug, I'm using the matlab routine 'read_surf' from the 3.0.3 distribution to read a surface generated by mri_tessellate. The magic number for the surface is: 16777213, which does not match either the QUAD or the TRI magic numbers listed in read_surf and hence does not read it. Is there an up

Hi Satra, I think the magic # should still be 16777215. Did your surface get corrupted somehow? Bruce On Thu, 13 Jul 2006, Satrajit Ghosh wrote: Hi Doug, I'm using the matlab routine 'read_surf' from the 3.0.3 distribution to read a surface generated by mri_tessellate. The magic number for

Hi Bruce, tksurfer can read the surface but matlab cannot. I'm therefore not sure if it is corrupted. I'm running on a 64 bit opteron, if that makes a difference. Satra -Original Message- From: Bruce Fischl [mailto:[EMAIL PROTECTED] Sent: Thursday, July 13, 2006 1:56 PM To: Satrajit

Have you tried opening it in excel? Alternatively, you can run aparcstats2table. This program was intended to be run on multiple subjects in order to produce a spreadsheet, but you can run it on one subject just as well. This is a fairly recent addition (within the last 8 weeks), so you might

I defined the label on the inflated surface, I don't know what the coordinates are mapped into when they are saved from tksurfer. I guess the vertex numbers go through a lookup into the orig surface to get those coordinates. When I ran the label2label mapping a second time, using the results of

Graham, In general, you should be careful when selecting the '-nosomething' options, as recon-all does not perform much checking for these flags (only the -autorecon1,2,3 flags contain the validity checks). An option when experimenting with the flags is to use the -dontrun flag, which just print
