These functions write a Read structure into a trace file. The principle format support is the SCF format.
Although reading is supported for ABI and ALF, writing is not. Additionally, it is possible to write
using the plain (old) staden format files or as Experiment files. In both these cases only the sequence
component of the trace file will be written.
When writing as an experiment file the QL, QR and SQ fields are generated from the Read structure. If we
previously created the Read structure from reading an experiment file then the original experiment file
data is also written. Otherwise EN, ID, LN and LT lines are also generated.
write_reading() writes a Read structure to the specified filename in the specified format. Formats
available are TT_SCF, TT_PLNand TT_EXP. Specifying format TT_ANY will be treated as TT_SCF.
fwrite_reading() writes a Read structure to the specified FILE pointer in the specified format. Apart
from writing to FILE pointer instead of a filename, the function is identical to write_reading().
