Yes -- the problem is that each 'mris_pmake' instance listens on a socket. This socket is used for communicating and controlling an mris_pmake instance that is already running.

If you open multiple 'mris_pmake's they will collide with the "Address already in use".

How to fix?

Each 'mris_pmake' instance reads an options file that controls its behavior. This file is called "options.txt" and resides in the same directory from which you started 'mris_pmake'.

Edit the file, and look for

# Control flags and settings controlPort = 1701

Change the controlPort to a different port and you should be fine. Of course, you'll need to probably start each of your 4 'mris_pmake' instances in separate directories so that they each get their own 'controlPort'.

There is a much simpler way to run 'mris_pmake' and even specify a script that it can execute using a python script called 'dsh' (also part of FreeSurfer). I will add some documentation to the FS wiki (but probably only at the end of November).

Regarding my first question in my previous post below, the same error occurs even when I run my script (containing many repetition of mris_pmake command) on only one terminal window.

Hi,

I'm trying to get distances on a cortical surface between sets of voxels in visual areas and I have two questions;

*1)*I have the following error message so often;

===

System error: Address already in use

Fatal error encountered.

SSocket `Unnamed SSocket_UDP_receive' (id: 0)

Current function: c_SSocket_UDP_receive::c_SSocket_UDP_receive

Problem binding to socket 1701

Error returned from system: Address already in use

Throwing exception to (this) with code 1

terminate called after throwing an instance of 'c_SSocket*'

I have around 10,000 voxel pairs to run mris_pmake( ) command. Since I have to call mris_pmake( ) so many times (one pair by one pair), I splitted the whole list of voxel pairs into four script files, containing many mris_pmake commands with 2,500 voxel pairs as arguments, then I ran scripts with four terminal windows saparately to parallelize the processing. All script files are located in the same diretory. Then I had the message as above. What might be the problem? (It seems as if multiple terminal instances share the socket port number)

*2)*How can I get interhemispheric distances between visual areas across hemispheres?
