It seems that seq to ab1 conversion is related export of DNA sequences or other similar data files between different formats. You will have to use specialized programs for that, such as the DNA Baser Sequence Aligner that typically offer a broad support for biochemistry files.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
