bwa trouble making index

10-16-2013, 08:01 AM

Hi,

While I was trying to make index for bwa, I encountered this error:

d-128-61-165:bwa-0.7.5a xxx$ ./bwa index -p EMCTargetbwaidx -a bwtsw EntamoebaCTarget.fa
[bwa_index] Pack FASTA... 0.00 sec
[bwa_index] Construct BWT for the packed sequence...
[BWTIncCreate] textLength=21312, availableWord=65536
Segmentation fault

First I thought it was some characters not allowed in the ">" line but it did not seem to be the case after I made very sure no special characters or space in the first line.

Wonder if anyone would enlighten me what the problem is.

Thanks

Wing

Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool

by SEQadmin2

CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.¹ But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

Despite this, “CRISPR helped turn genome editing from a specialized...

Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems

by SEQadmin2

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
