Problems compiling fcma-toolbox

[acamargofb]

I am having problems compiling the fcma-toolbox I did the following:

1. sudo cmake CMakeList.txt
2. sudo make and I got the following errors: .. . . [ 82%] Building CXX object CMakeFiles/FCMA.dir/src/FisherScoring.cc.o [ 86%] Building CXX object CMakeFiles/FCMA.dir/src/LibSVM.cc.o [ 91%] Building CXX object CMakeFiles/FCMA.dir/src/main.cc.o [ 95%] Building CXX object CMakeFiles/FCMA.dir/src/Marginal_Scheduler.cc.o [100%] Linking CXX executable FCMA CMakeFiles/FCMA.dir/src/Scheduler.cc.o: In function DoSlave(int, int, trial_data_t*, trial_data_t*, Task, trial_t*, int, int, int, int, int)': Scheduler.cc:(.text+0x124): undefined reference to ompi_mpi_comm_world' Scheduler.cc:(.text+0x12b): undefined reference to ompi_mpi_int' Scheduler.cc:(.text+0x189): undefined reference to MPI_Recv' Scheduler.cc:(.text+0x190): undefined reference to MPI_Wtime' Scheduler.cc:(.text+0x1ec): undefined reference to MPI_Wtime' Scheduler.cc:(.text+0x1fd): undefined reference to ompi_mpi_float' Scheduler.cc:(.text+0x221): undefined reference to MPI_Send' Scheduler.cc:(.text+0x23e): undefined reference to MPI_Send' Scheduler.cc:(.text+0x249): undefined reference to ompi_mpi_float' Scheduler.cc:(.text+0x25f): undefined reference to MPI_Send' Scheduler.cc:(.text+0x2e9): undefined reference to MPI_Wtime' Scheduler.cc:(.text+0x2fa): undefined reference to ompi_mpi_float' Scheduler.cc:(.text+0x321): undefined reference to MPI_Send' Scheduler.cc:(.text+0x33e): undefined reference to `MPI_Send' . . .

Does somebody know how to fix this issue ?

Have a nice day,

It looks like that your system doesn't have MPI packages. I would recommend you check out the FCMA component of BrainIAK, which has better support and should be easier to install and run.

Do you know or someone how to solve the issue with the MPI packages. I have installed with sudo apt-get install and also from the code with configure Best, Aldo

You may check if the MPI library is correctly linked while compiling FCMA. It seems to me that the system doesn't find corresponding libraries even if you have installed somewhere.

Hi Yida Wang:

I solved the problem of compilation, I have to change the CMakeFile.txt, this part: ... set (EXTRA_LIBS ${EXTRA_LIBS} svmphi svmsimple niftiio znz mpi OpenCL blas openblas boost_system hdf5_serial boost_iostreams z hdf5_serial_hl boost_serialization boost_mpi)

...

Best regards,

Aldo

Hi Yida:

I have a question:

I would like to use this toolbox to do a correlation between tfn and rfn defined like this:

tfn = 'aal_tpl.nii'; % ROI filename rfn = 'swrfunc.nii'; % resting state fMRI

How can I do that with this toolbox?

Thanks a lot in advance,

Aldo

Aldo,

If you would like to leverage HPC to do some correlation computation quickly, I would recommend you to refer to FCMA@BrainIAK again. We have example code for high-performance correlation computation at https://github.com/IntelPNI/brainiak/blob/master/examples/fcma/corr_comp.py

Hope it helps, Yida
