fastq-dump SRR1042xxx.sra
2018-05-30T16:07:44 fastq-dump.2.9.0 err: file invalid while opening directory within file system module - failed SRR1042xxx.sra

=============================================================
An error occurred during processing.
A report was generated into the file '/home/xxx/ncbi_error_report.xml'.
If the problem persists, you may consider sending the file
to 'sra@ncbi.nlm.nih.gov' for assistance.
=============================================================

解决：问题很简单，就是sra文件没有下载完整，重新下载；遇到这种问题，也是佩服自己运气了。
在文件下载一半的时候，就使用fastq-dump转换格式，报同样的错误。
