I am trying to install FreeSurfer: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0/freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0.tar.gz

I am following these steps to install FreeSurfer: https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall

When I run following commands:

freeview -v 

    bert/mri/T1.mgz 

    bert/mri/wm.mgz 

    bert/mri/brainmask.mgz 

    bert/mri/aseg.mgz:colormap=lut:opacity=0.2 

    -f 

    bert/surf/lh.white:edgecolor=blue 

    bert/surf/lh.pial:edgecolor=red 

    bert/surf/rh.white:edgecolor=blue 

    bert/surf/rh.pial:edgecolor=red

I get this error:

freeview.bin: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

And when I am trying to install this package:

sudo apt-get install libpng12.so.0

I am getting this error:

Reading package lists... Done

Building dependency tree       

Reading state information... Done

E: Unable to locate package libpng12.0-0:i386

E: Couldn't find any package by glob 'libpng12.0-0'

E: Couldn't find any package by regex 'libpng12.0-0'

I am totally new to Linux, please help!

The software you are trying to run requires version 12 of libpng, which is no longer available in Ubuntu 16.10+. The best thing to do would be to install Ubuntu 16.04, or maybe let the developers of the software know about this problem so they can provide a version compatible with Ubuntu 16.10.

Download the shared library from
https://packages.ubuntu.com/xenial/amd64/libpng12-0/download and then run
sudo dpkg -i

I was having problems installing SAS on Ubuntu 18.04. Some instructions following will only apply to those installing SAS.

The first problem was that the installation would hang on hot fix W83001. Solution is to move hot fix W83001pt.zip out of the <depot>/hot_fix directory so it is not installed.

The second problem was that the following package was needed and not installed by default on Ubuntu: libjpeg.s0.62. Installation was done as follows:

sudo apt install libjpeg62

The third problem was the missing package discussed on this page, libpng12.so.0. It was downloaded from the link above and installed as follows:

sudo apt install ./libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

After this, I was able to run the SAS software. Thanks everyone for posting the tips.

You can find this package at

64b
http://packages.ubuntu.com/xenial/amd64/libpng12-0/download

32b
https://packages.ubuntu.com/xenial/i386/libpng12-0/download

download source code https://packages.ubuntu.com/xenial/libpng12-0

compile and install :

wget http://archive.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng_1.2.54.orig.tar.xz



tar xvf  libpng_1.2.54.orig.tar.xz 



cd libpng-1.2.54

./autogen.sh

./configure

make -j8 

sudo make install

Another alternative is to create symbolic links to both PNG and JPEG libraries

sudo ln -s -T /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib/x86_64-linux-gnu/libjpeg.so.62

sudo ln -s -T /usr/lib/x86_64-linux-gnu/libpng16.so /usr/lib/x86_64-linux-gnu/libpng12.so.0

It will generate some warnings (libpng warning: Application built with libpng-1.2.7 but running with 1.6.28) when running. However, Freeview works ok.
