The following error messages appear after I ran deSALT aln:

[Main] deSALT - De Bruijn graph-based Spliced Aligner for Long Transcriptome reads [Param-INFO] deSALT parameters:index-kmer:22 seed-lmer:15 hash-kmer:8 thread:2 strand_diff:20 identify junction:both_strand [Phase-INFO] Loading Index and Reads [Phase-INFO] Seeding and Chaining Phase (first-pass) [Skeleton-generation] Generating skeletons of 99485 reads, total 241286245 bases in 62.112282 seconds [Phase-INFO] Total 99485 reads were processed in 62.352 seconds (first-pass) [Phase-INFO] Refined Alignment Phase (second-pass) [Phase-INFO] Exons inference by skeletons of all reads [Phase-INFO] Inferring total 84570 isolated regions (pseudo-exons) after merging and filtering [Phase-INFO] Refining pseudo-exons by scoring matrix [Loop-ProcessReads] The 0st loop of refined alignment procedure with 49744 reads......

How can I solve this? Thank you!
