Alpha and Beta Development Versions of IMOD (IMOD 4.6.x)
Package Archive - Older Versions of IMOD
If you have a 64-bit version of Ubuntu, or recent Fedora Core, 32-bit versions of IMOD will not work and you must use a 64-bit version.
To use a GPU for computing, see IMOD Guide for more details about which packages work with which NVIDIA driver versions and operating system versions. The package built with CUDA 6 requires drivers with version 331 or higher.
Red Hat Enterprise Linux 6 64-bit: Download IMOD 4.7.15 for 64-bit systems (built under RHEL6, should work for Fedora Core 12 onward, and other current Linux versions including Ubuntu). This package is built with CUDA 6.0 and should be used if you have drivers that support CUDA 6.
Red Hat Enterprise Linux 6 64-bit: Download IMOD 4.7.15 for 64-bit systems (built under RHEL6, should work for Fedora Core 12 onward, and other current Linux versions). This package is built with CUDA 4.1.
Red Hat Enterprise Linux 7 64-bit: Download IMOD 4.7.15 for 64-bit systems (built under Centos 7). This may be the best package to install for RHEL7 and recent Fedora, but should not be used for Ubuntu. This package is built with CUDA 6.5, not 6.0. If your drivers only support CUDA 6.0 (e.g., version 340), use the RHEL6 package.
Red Hat Enterprise Linux 5 64-bit: Download IMOD 4.7.15 for 64-bit systems (built under RHEL5, should work for Fedora Core 6 onward, Suse 10.3, and other somewhat older Linux versions). This package is built with CUDA 3.1.
Red Hat Enterprise Linux 5 32-bit: Download IMOD 4.7.15 for 32-bit systems (built under RHEL5, should work for Fedora Core 6 onward and Suse 10.3).
Latest Stable Release Packages - Mac
These packages of IMOD 4.7 run only under 64-bit systems with Intel processors. If you want to use a GPU for computing tomograms, and you either have a Quadro 4000 or are running OS X 10.7 or higher, you must use a version built with CUDA version 4 or 6. The package built with CUDA 6 should be used if you have CUDA 6 drivers.
The file that you download cannot be clicked on to install it; see the IMOD Guide for instructions on running it at the command line.
Mac OS X 10.8 - 10.11: Download IMOD 4.7.15 for Mac OS X 10.8 - 10.11. This package was built on 10.8 with CUDA version 6; it should also work on 10.7.
Mac OS X 10.8 - 10.11: Download IMOD 4.7.15 for Mac OS X 10.8 - 10.11. This package was built on 10.8 with CUDA version 4; it should also work on 10.7.
Mac OS X 10.5 - 10.6 with CUDA 3: Download IMOD 4.7.15 for Mac OS X 10.5 - 10.6 with CUDA version 3. This package was built on 10.6 with CUDA version 3 and supports computing with the GPU on 10.5 or 10.6.
Mac OS X 10.6 - 10.7 with CUDA 4: Download IMOD 4.7.15 for Mac OS X 10.6 - 10.7 with CUDA version 4. This package is needed for computing with the GPU under 10.7 or under 10.6 with a Quadro 4000 card.
Latest Stable Release Packages - Windows
These packages work on all versions of Windows from Windows 2000 through Windows 10. The 64-bit packages will not work with 32-bit Windows. You need to have either Cygwin or Python installed to install IMOD; see below. The package built with CUDA 6 should be used if you have drivers that support CUDA 6.
Windows 64-bit with CUDA 6.0: Download clickable installer, command-line self-installing file, or compressed tar file of IMOD 4.7.15 for 64-bit Windows versions, built with CUDA 6.0, and should be used if you have drivers supporting CUDA 6.
Windows 64-bit with CUDA 4.1: Download clickable installer, command-line self-installing file, or compressed tar file of IMOD 4.7.15 for 64-bit Windows versions, built with CUDA 4.1.
Windows 64-bit with CUDA 3.0: Download clickable installer, command-line self-installing file, or compressed tar file of IMOD 4.7.15 for 64-bit Windows versions, built with CUDA 3.0.
Windows 64-bit with CUDA 2.1: Download clickable installer, command-line self-installing file, or compressed tar file of IMOD 4.7.15 for 64-bit Windows versions, built with CUDA 2.1. Use these packages if you want to use the GPU and cannot upgrade your NVIDIA drivers to the required level to use a package built with CUDA version 3.
Windows 32-bit: Download clickable installer, command-line self-installing file, or compressed tar file of IMOD 4.7.15 for Microsoft Windows. These packages are built with CUDA 3.0.
Older libpng for Red Hat/Centos 7 and Recent
Fedora
As of August 31, 2014), the RHEL6 packages now include a libpng compatible with the Qt version in the package, so it should no longer be necessary install version 1.2 of libpng for recent Fedora.Red Hat/ Centos versions.
Installing on Ubuntu and Debian Linux
A few steps are different when installing on Ubuntu, and these are described at various places in the installation instructions in the IMOD Guide. In essence:
If SELinux is enabled, the IMOD installation script will attempt to change the
security context of the IMOD libraries if appropriate. If problems still
occur with SELinux, please report them.
The sign of trouble with SELinux is a message "cannot restore segment prot
after reloc: Permission denied" when trying to run an IMOD program.
To disable SELinux, change /etc/selinux/config
so that it says SELINUX=disabled.
You must have a Java run-time environment (JRE) installed to run the eTomo interface for building tomograms. See the IMOD Guide for details about whether the Java available in your version of Linux will work with eTomo. Java 1.6 or later is required for IMOD 4.7. If you need to install Java for Windows or Linux, get the latest Java Run-time Environment from the Java download site.
Cygwin for Using IMOD under Windows
For complete IMOD functionality under Windows, you need to install either the Cygwin toolkit or Python (see next section). To simplify the process of installing Cygwin, we provide both a Cygwin installer for the easiest possible initial installation, and also a package that you can install from (these two packages are from October 2014, after the Shellshock bug in bash was fixed). You can also use the latter package to upgrade from an earlier package that we provided. When you upgrade, you may see an alarming warning about mount point changes; this is not relevant for typical usage of Cygwin.
IMOD 4.7 should work reliably with the current version available from Cygwin, even on 64-bit systems. However, the Python executable in current versions is not named python.exe, which is problematic. If you reinstall IMOD after upgrading Cygwin, the IMOD installer will take care of this; otherwise, see the IMOD guide.
To satisfy the terms
of the Cygwin open source license, we also provide the
source code matching the binaries in our package.
Python and Psutil for Using Windows IMOD without Cygwin
To use IMOD fully without Cygwin on Windows, you need to install Python and a module called psutil built for the same version of Python. You do not need these packages if you are using Cygwin. The IMOD installer in IMOD 4.7 and beta releases through IMOD 4.8.48 will not be able to find 32-bit Python on 64-bit Windows 7 or 64-bit Python on 64-bit Windows 8 or 10; so use only a 64-bit Python on 64-bit Windows 7, or a 32-bit Python on 64-bit Windows 8 or 10. These installers also will not be able to find Python 3.5. These restrictions should no longer apply for IMOD 4.8.49 and above. Some packages are provided here:
See the IMOD guide for further instructions. The short version: use a 32-bit Python 3 package for a 32-bit system or 64-bit Windows 8 or 10; use a 64-bit Python 3 package for 64-bit Windows 7; install Python first and install for all users; to install psutil on Windows Vista/7/8/10, you need to right-click and "Run as Administrator".
The download packages ending in .csh or .sh
have been archived with tar, compressed with gzip, and packed with a C
shell or sh script that will install or upgrade IMOD in the recommended location.
They must be run as scripts at the command line and cannot be installed by
clicking on them. The Windows installer packages ending in .exe
can be run by clicking on them.
For instructions on unpacking, installing and setting up
the IMOD environment, see the IMOD User's
guide.
All packages for Linux now contain a copy of the Qt library
that will be used when running IMOD. It is not placed on the
LD_LIBRARY_PATH so it will not interfere with the use of the
Qt library on the system or in other packages.
imodhelp at the command line, or from the help facilities
of eTomo, 3dmod, etc.
Our ftp site contains development versions of IMOD that we have released to our local users. See the README file or the list of changes for details. To download a file, right click on it and then select "Save Link as..." or "Save Target as...". Double-clicking will load it into your browser.
Click here for the beta versions, which have generally been running for at least a few days. The alpha subdirectory has the packages when they are first released.
If you have trouble installing the csh file, it may be due to a bad download. Access the directory with this http link instead.
We also make our nightly builds from the current source available. There will often be bugs in these packages, so generally you should not use one unless you have been told to try it. Here they are.
If you use a development version, the best source of documentation is in the
package itself, available through the imodhelp command.
Click here to access all documentation in
the latest development version, updated nightly.
