Bad gradients cannot be manual exclusion
Hi,

When I want to exclude the bad gradients when Visual Check, I select "Exclude" in the pop-up box to remove the bad gradients, then select the "Save Dwi and QCResult" button under "Manual Checking" to save the changes. But the pop-up box shown "No Processing done", and the changes can not be saved.  

This error was shown in the terminal: DTIPrep[31294:507] modalSession has been exited prematurely - check for a reentrant call to endModalSession

Any suggestion would be appreciate. Thanks.

Hi Huanjie

Which platform and which version of DTIPrep are you using?

Hi Martin,

I also met the same problem. I am currently using the DTIPrep1.2.4_linux64 (Qt4).

When I select Exclude and try to save it. The pop-up box shown "No Processing done", and the changes can not be saved.
The terminal showed:
VC_Status.size(): 32
index:0 VC_Status: -1
index:1 VC_Status: -1
index:2 VC_Status: -1
index:3 VC_Status: -1
index:4 VC_Status: -1
index:5 VC_Status: -1
index:6 VC_Status: -1
index:7 VC_Status: -1
index:8 VC_Status: -1
index:9 VC_Status: -1
index:10 VC_Status: -1
index:11 VC_Status: -1
index:12 VC_Status: -1
index:13 VC_Status: -1
index:14 VC_Status: -1
index:15 VC_Status: -1
index:16 VC_Status: -1
index:17 VC_Status: -1
index:18 VC_Status: -1
index:19 VC_Status: -1
index:20 VC_Status: -1
index:21 VC_Status: -1
index:22 VC_Status: -1
index:23 VC_Status: -1
index:24 VC_Status: -1
index:25 VC_Status: -1
index:26 VC_Status: -1
index:27 VC_Status: -1
index:28 VC_Status: -1
index:29 VC_Status: -1
index:30 VC_Status: -1
index:31 VC_Status: 6

What can I do to save this change?

Thank you very much,

RE: Bad gradients cannot be manual exclusion
I have another problem when I was trying to exclude the bad gradients. After I clicked "Visual check", and then click "exclude", the GUI will automatically closed. I tried this on my mac, both DTIprep 1.2.4 and 1.2.7 have this problem. I wonder whether there is some method can deal with this, or can this step can be done by command?
Thank you so much for any suggestions. 
Thanks.
