fastqc Exception (error)

[frymor]

Hi,

I am running the fastqc (v0.11.4) on Ubuntu 14.04.3 LTS.
I have four fastq files (two pairs of paired-end reads samples). They are AFAIK from old solexa machines in sanger format
somehow when I am trying to fastq the _1 files I get the following error message:

fastqc -t 12 -o ../Results/1c3c603f-29ac-4263-851d-b19f9ce4cfb0/fastqcResults/ 61627AAXX_1_1.fastq.gz 
Started analysis of 61627AAXX_1_1.fastq.gz
Exception in thread "Thread-1" java.lang.IllegalArgumentException: Unexpected cs char C

        at uk.ac.babraham.FastQC.Analysis.AnalysisRunner.run(AnalysisRunner.java:76)
        at java.lang.Thread.run(Thread.java:745)

than nothing happens.
When I am using the same command for the _2 files, it works fine.

fastqc -t 12 -o ../Results/1c3c603f-29ac-4263-851d-b19f9ce4cfb0/fastqcResults/ 61627AAXX_1_2.fastq.gz 
Started analysis of 61627AAXX_1_2.fastq.gz
Approx 5% complete for 61627AAXX_1_2.fastq.gz
...

I can't see any differences in the format of the two files.

the header of the two files from one of the pairs looks like that:

zcat 61GAFAAXX_1_1.fastq.gz | head -n 12
@SOLEXA12_1:1:1:990:4777/1 1:Y:0:0

and

zcat 61GAFAAXX_1_2.fastq.gz | head -n 12
@SOLEXA12_1:1:1:990:4777/2 2:Y:0:0

Any ideas, why I can't run the _1 files?

thanks
Assa

P.S.
When I am running the SolexaQA++ tool, I can read all the four files without difficulties.
