Classification of ROIs and error correction. All ROIs were first classified (A) and produced FL and nFL isoform sequences with differential patterns of length distribution (B). After the error correction by Illumina short reads, ROIs were categorized according to the occurred locations of erroneous fragments (C), including the absence (No), terminal ends (End), inner positions (Inner) and the entire sequences (Entire). Finally, we investigated the length proportion of erroneous fragment relative to raw ROIs (D).
