The C++ coded tool
solid2fastq in the package BFAST was able to merge native SOLiD files (i.e.,
file_QV.qual) into a colorspace-encoded FastQ format. Specifically, the sequences remained in colorspace, but the quality values were re-formatted to abide to FastQ specifications.
BFAST has not been maintained for years (see GitHub record), and compiling it fails at multiple points, including at the compilation of the above-mentioned tool
Hence, does someone know an alternative tool or script to conduct the above-mentioned merger? The process is a simple string operation, and there are probably several similar Python- or Perl-scripts saved out there in GitHub space that do it.
P.S. Post Transforming And Manipulating Color Space Reads does a wonderful job in explaining the different colorspace-related conversion processes and has become the main go-to reference on this topic.
