Makefile is text file that is read if executing make command. make is Command that performs compile in the order determined automatically, even if there are various files as C language source code. On Eos, commands are summarized by using make, and perform large-scale works (Single particle analysis or Electron tomography ...). On purpose of distributed environment, stream processing, and improvement of the degree of freedom of the input and output, we are developing POINE as make of next generation.

Makefile on Eos

part of Makefile

When performing 3D Reconstruction on Eos, if number of files is a large amount, It is necessary to a great deal of effort in how to enter Commands one at a time. In order to reduce this effort, make command is used in many cases on Eos. And knowledge of shell script is also required in order to understand the makefile.

.ref3d.red2d:　(1)
        mrc3Dto2D -i $*.ref3d -o $*.ref2d -EulerMode YOYS InterpolationMode 0 -Rot1 0 359 $(STEP) -Rot2 0 359 $(STEP) -Rot3 0 0 $(STEP) -m 1

For example, when there is a Makefile as described above,

$ make EM.ref2d

If you execute as above the make command, it looks for a line that generates the extension .ref2d and performs automatically.

This time, it means that a part (1) generates .ref2d file from .ref3d file, thus it performs command as the following.

mrc3Dto2D -i $*.ref3d -o $*.ref2d -EulerMode YOYS InterpolationMode 0 -Rot1 0 359 $(STEP) -Rot2 0 359 $(STEP) -Rot3 0 0 $(STEP) -m 1

As meaning that this row belongs to the previous (1), Tab blank is inserted at the beginning. Thus, as long as there is a Tab blank, it means that it belongs to X.

In addtion, Makefile that makes make is able to performing to multiple works by only one make command like the following. Thus, Makefile is a necessity in works (as 3D Reconstruction) that requires multiple steps.

All::
       make $(TARGET).ref3d;
       make $(TARGET).ref2d;
       make AVGs;
       make -j $(JOP_NUM) corinfo;
       make CORINFOs;
       make $(TARGET).ds6;
