Hi Sravan , please post to the list and not to us personally. Thanks!
This is just a list of what you (or whoever you are working with acquired), so I don't know what is in there. Probably #2 is what you want, less sure about #4

Hello Doug,

Are no. 2 and no. 4 the T1s ? which one do I need to pass to the recon-all ? Thank you very much for your response. It helps a lot.

They do not have to have a dcm extension. The 180 files represent many slices from a single volume (or multiple volumes). You need to find out which ones are which. One way to do this is to run
dcmunpack -src path-to-dicom folder
this will look through all the folders and files under path-to-dicom and sort them into acqusitions. It will print out a list of each volume and a single dicom file that belongs to that volume. When you find the T1 that you want to run thru FS, pass that single dicom file to recon-all with the -i flag

I ran recon-all got an error. the error.log file has "MRIresample(): sourcematrix has zero determinant; matrix is:"
Am I on the right path ? or am I missing something ? So I need to convert the images before runningthe recon ? I see that only 8 files in the first folder in the series are being read, Do I need to input the files in a different structure ?
