External Email - Use Caution        

Hi Ishi,

Following are what I gathered:

- You're running Freesurfer 7.1.1 on an ubuntu 20.04 box
- Ubuntu 20.04 has libncurses 6 installed as default
- Freesurfer 7.1.1 is linked against libncurses 5
- So previously you were advised to install libncurses5-dev
- And you followed the advice
- But somehow your ubuntu is failing to find the shared object file of that library

It seems your installation of libncurses5-dev is somehow hosed.
Could you please double check if libncurses5-dev is successfully installed
by running the following commands one at a time?
(You don't need to be root to run them.)

apt list --installed *ncurses*
find /lib -name 'libncurses*'
find /usr/lib -name 'libncurses*'
find /usr/local/lib -name 'libncurses*'

Best

Hello experts, 

With reference to my previous email, I am attaching the log file of segmentHA_T1.sh bert command.

Please provide your feedback.

Thanks in advance.

Hello experts, 

The recon-all command executed without any errors.

However, on following the subsequent  command segmentHA_T1.sh bert, it gives me an error (even after modifying my .bashrc & .profile  with export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freesurfer/MCRv84/sys/os/glnxa64).

Also, I have tried sudo apt-get install libncurses5-dev. But that doesn't seem to resolve the issue.

P.s - The error is attached below for reference.

Thanks in advance.

Hello, 

Thanks for those suggestions.
I already seem to have modified my bashrc with the same command. 

But I think running as root was a problem. 
But that's weird as earlier none of the Fs commands were executed without root. 

But now that seems to work.
 However, I still need to check with segmentHa_T1 if that works well after recon-all.

Thanks for your help.

And you seem to be running FreeSurfer as root.
Since that could complicate matters, could you run it as a normal user?

Best,

Hi Ishi,

I'm actually not a FreeSurfer developer and this question seems beyond me, but my googling leads to this page:

which seems to suggest that you add the following to your .bashrc, .profile or similar places and retry.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/freesurfer/MCRv84/sys/os/glnxa64

Please try this and report your result.
If this doesn't work, hopefully a FreeSurfer developer would chime in.

Best,
Horsng

Hello, 

I am sorry for posting up another thread. Had an issue with subscription so had to post again (will keep it in mind now). 

I tried that out. And that worked well. 

But there's another error that pops up after I run (attached in the image): -
recon-all -all -s bert

I tried the following commands in order to update libstd. 
apt-get update
apt-get install libstdc++6
But that didn't work. 

I am not able to trace the exact error. 

Thanks for the help.

Hi Ishi,

You apparently omitted an "n": it must be libncurses5-dev (please note the n after lib).

And please try to keep previous correspondences intact,
as otherwise the devs must hunt the mail archive for the detail.

Best,
Horsng

Hello experts,

In response to the previous email about matlab installation error while attempting to use hippocampal subfields. 

I tried the following command as suggested by you :- 

sudo apt-get install libcurses5-dev
 
But I get the following error :- 

Reading package lists... Done 
Building dependency tree Reading state information... Done 
E: Unable to locate package libcurses5-dev 

Also, I am using fs version 7.1.1. 
I installed freesurfer-linux-centos7_x86_64-7.1.1.tar.gz file.
