External Email - Use Caution        

Hi, E

Thanks for your reply, I used one core and its associated RAM from the server,(I guess is not very much) but I have solved it by assigning more RAM memory.

Best,
Wei

Dear Wei,

Sorry for missing your message (it happens sometimes…).

The longitudinal subfield module is very RAM memory hungry.

How much RAM memory do you have (not disk space, these are different things).

Cheers,

/Eugenio

Hello, Dear Freesufer experts 

 

I just thought of sending a friendly reminder - 

 

I am wondering if you had the time to go over my question? 

 

Best regards,

Wei

For more details, see the log file /home/weishao/long_BAY12019/scripts/long-hippocampal-subfields-T1.log



I have checked the space:

Could you tell me what I should do? Thanks
