BWA and BWA MEM can't process several files with reads

1. Tools -> NGS data analysis -> Map reads to reference.
2. Choose BWA or BWA MEM.
3. Reference: _common_data/bwa/index1/ecoli.fa.amb.
4. Reads:
   • _common_data\e_coli\e_coli_reads/e_coli_1_1.fastq
   • _common_data\e_coli\e_coli_reads/e_coli_1_2.fastq
5. Click Start.
6. Click Import.
   => Error appears: Truncated file: "ecoli.sam"Document was removed.

Another scenario:

1. Tools -> NGS data analysis -> Map reads to reference.
2. Choose BWA or BWA MEM.
3. Reference: _common_data/bwa/index1/ecoli.fa.amb.
4. Set "Paired-end".
5. Reads:
   • _common_data\e_coli\e_coli_reads/e_coli_1_1.fastq [Upstream]
   • _common_data\e_coli\e_coli_reads/e_coli_1_2.fastq [Downstream]
   • _common_data\e_coli\e_coli_reads/e_coli_2_1.fastq [Upstream]
   • _common_data\e_coli\e_coli_reads/e_coli_2_2.fastq [Downstream]
6. Click Start.
   => Error appears: In paired-end mode it possible to analyze only 2 read sets using BWA.

So, it is possible to set this data, but it is impossible to get result. The same is in WD.
