1. Setup of new merlin

    New merlin

    Just got a new virtual machine running on FMF's servers installed.

    Some data from Feri:

    med0.ipv6.fmf.uni-lj.si
    
    u: xxxxxxx
    p: xxxxxxx
    
    Ta uporabnik ima polne sudo pravice.
    
    Trenutno ipv6 naslov ni dostopen iz Interneta, samo iz FMF omrezja.
    
    Za virtualko je skonfiguriran reverse proxy (na …

  2. FFT root package

    FFT in root

    While FFT is adopted in ROOT, it is sometimes tedious to interpret the results of the transformation. To faciliate the procedure I invested some time in creating an independent FFTdata_ROOT class which handles the data and transformation of a real valued function given as histogram.

    The package …

  3. Installing JTAG on Ubuntu

    Programing MADDAQ Xilinx

    To program the FPGA you should open Impact:

    shell #>~/scripts/run_impact.sh

    and you will have a chain like the one in the picture

  5. Usage of reconstruction software

    README for observer_tools software

    The package observer_tools is intended for analysis and reconstruction of probe data. The package is pretty disorganized in its current versions as it was heavily modified to suit particular goals that came about during reconstruction.

    The package consists of three modules:

    • observer module. This module contains …

    How to evaluate phantom data

    For SNR one needs to determine the expected data projection

    $$\bar{Y}=M\lambda$$

    where $\lambda$ is the true object (digital reference object, say)
    and M is the system matrix. Moreover, one needs the average reconstructed image $\check{\lambda}$ which is the reconstruction of $\bar …

  7. High res PET calibration

    Process si calibration run

    Parse the data using observer and decoderSiSparse. Typical configuration file processSi257.config looks like this:

    #run with decoderSiSparse
    files=/storage/data/20161206/si/Am241_si257_thr180_adj3_
    eventsDotOut=/storage/data/20161206/si/out/Am241_si257_thr180_adj3.out
    nPedestal=10000
    configFile=/storage/data/imageRec/layout/setupOSU/setup257.in
    

    The configuration file setup257 …
