==Where can I download Slicer?==
3DSlicer is available for download by visiting the following link:  http://download.slicer.org

==Is slicer really free?==

Yes, really, truly, free.  Not just a free trial.  No pro version with all the good stuff.  Slicer is free with no strings attached.  You can even re-use the code in any way you want with no royalties and you don't even need to ask us for permission.  (Of course we're always happy to hear from people who've found slicer interesting).

See [http://www.slicer.org/pages/LicenseText the Slicer License page] for the legal version of this.

==Can I use slicer for patient care?==

Slicer is intended for research work and ''has no FDA clearances or approvals of any kind''.  It is the responsibility of the user to comply with all laws and regulations (and moral/ethical guidelines) when using slicer.

*On the Mac, remove the Slicer.app file. To clean up settings, remove "~/.config/www.na-mic.org/"
*On Linux, remove the directory where the application is located. To clean up settings, remove "~/.config/NA-MIC/"

== Where can I find Slicer tutorials? ==
Slicer tutorials associated with the latest {{documentation/currentversion}} stable release are available by visiting the following link:  [[Documentation/Nightly/Training|Click Here]].

==I read errors in the logs complaining about memory==

Errors such as “Description: Failed to allocate memory for image.” indicate that you don’t have enough memory space.
This can be a common issue if you run a 32-bit version of Slicer. You cannot expect a 32-bit executable to deal with any moderately complex problem. The [[Documentation/{{documentation/version}}/SlicerApplication/HardwareConfiguration#32_bit_versus_64_bit|recommended solution]] is to download/build/use Slicer in 64-bit mode.
 
Possible workarounds:
* Use a 64-bit version of Slicer 
* You have somewhat more memory if you run the module in a separate process. To do that open [[Documentation/{{documentation/version}}/SlicerApplication/ApplicationSettings#Modules|Edit / Application Settings / Modules]] and check the “Prefer Executable CLIs” option, then restart Slicer.
* Decrease the size and/or resolution of the input and output images
** Consider [[Documentation/{{documentation/version}}/Modules/Crop_Volume|Crop Volume]] to focus on just your area of interest.
** Consider [[Documentation/{{documentation/version}}/Modules/ResampleScalarVectorDWIVolume|ResampleScalarVectorDWIVolume]] or [[Documentation/{{documentation/version}}/Modules/ResampleScalarVolume|ResampleScalarVolume]] increase the sample spacing (decrease the resolution) of your data.
