0006811: FASTA Header Truncated at First Space During Import in MEGA
When importing FASTA files into MEGA12, the software truncates the sequence header at the first space character. As a result, the full description of the sequence is not preserved in the imported data.
Example:
PQ247226.1:50-1452 Pseudomonas sp. strain DTS1 16S ribosomal RNA gene, partial sequence

Imported result:
PQ247226.1:50-1452
