• Binary files

Atom_struct_utils plugin is a pure Python module but uses the program "maxit" for conversion of pdb/cif files with atomic coordinates. If not available maxit will be instaled. Prerequisites for maxit are bison, flex, csh and tcsh

sudo apt install bison  (command valid for ubuntu/debian and similar OS)
sudo apt install flex   (command valid for ubuntu/debian and similar OS)
sudo apt install tcsh   (command valid for ubuntu/debian and similar OS)

• Tests

To check the installation, simply run the following Scipion test:

• scipion test --grep TestOperate --run
• scipion test --grep TestConvertSymmetry --run

Examples

See Model Building Tutorial

Problem compiling maxit?

Try:

• install bison, flex, csh, tcsh
• edit the file ./cifparse-obj-v7.0/Makefile (in scipion/software/em/maxit-version) and replace "mv" by "cp"
