Hello David and others, After reading the preprint of the RazerS3 paper, I am really looking toward testing the tool ! From the readme it says that it can be installed in binary form or from source code. In the subversion source tree, there is razers 1.1 and razers 2: [sboisver12@colosse1 software]$ grep RazerS seqan/core/apps/*/*.cpp |grep version seqan/core/apps/micro_razers/micro_razers.cpp: cerr << "MicroRazerS version 0.1 20090710 (prerelease)" << rev << endl; seqan/core/apps/razers2/razers.cpp: addVersionLine(parser, "RazerS version 2.0 20110518 [" + rev.substr(11, 4) + "]"); seqan/core/apps/razers/razers.cpp: addVersionLine(parser, "RazerS version 1.1 20100618 [" + rev.substr(11, 4) + "]"); seqan/core/apps/splazers/splazers.cpp: addVersionLine(parser, "RazerS version 1.1 20100618 [" + rev.substr(11, 4) + "]"); And the distributed binary 'razers --help' produces this on my system: [sboisver12@colosse1 linux64]$ ./razers3 --help *** glibc detected *** ./razers3: double free or corruption (out): 0x00000000008d8140 *** ======= Backtrace: ========= /lib64/libc.so.6[0x396e27245f] /lib64/libc.so.6(cfree+0x4b)[0x396e2728bb] /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6(_ZNSs9_M_mutateEmmm+0x1bf)[0x2aed46c40aef] /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6(_ZNSs15_M_replace_safeEmmPKcm+0x2c)[0x2aed46c40b2c] ./razers3(_ZN5seqan13RazerSOptionsINS_10RazerSSpecILb0ELb0EEEEC1Ev+0x1d2)[0x57a702] ./razers3(main+0x27)[0x68d147] /lib64/libc.so.6(__libc_start_main+0xf4)[0x396e21d994] ./razers3[0x53a449] ======= Memory map: ======== 00400000-006d8000 r-xp 00000000 c96:9a5e 272865020 /rap/nne-790-ab/software/RazerS/v3.0-beta1/razers3.0-beta1/linux64/razers3 008d7000-008d8000 rw-p 002d7000 c96:9a5e 272865020 /rap/nne-790-ab/software/RazerS/v3.0-beta1/razers3.0-beta1/linux64/razers3 008d8000-008da000 rw-p 008d8000 00:00 0 04efd000-04f1e000 rw-p 04efd000 00:00 0 [heap] 396de00000-396de1c000 r-xp 00000000 08:01 27394050 /lib64/ld-2.5.so 396e01c000-396e01d000 r--p 0001c000 08:01 27394050 /lib64/ld-2.5.so 396e01d000-396e01e000 rw-p 0001d000 08:01 27394050 /lib64/ld-2.5.so 396e200000-396e34e000 r-xp 00000000 08:01 27394052 /lib64/libc-2.5.so 396e34e000-396e54e000 ---p 0014e000 08:01 27394052 /lib64/libc-2.5.so 396e54e000-396e552000 r--p 0014e000 08:01 27394052 /lib64/libc-2.5.so 396e552000-396e553000 rw-p 00152000 08:01 27394052 /lib64/libc-2.5.so 396e553000-396e558000 rw-p 396e553000 00:00 0 396ea00000-396ea82000 r-xp 00000000 08:01 27394082 /lib64/libm-2.5.so 396ea82000-396ec81000 ---p 00082000 08:01 27394082 /lib64/libm-2.5.so 396ec81000-396ec82000 r--p 00081000 08:01 27394082 /lib64/libm-2.5.so 396ec82000-396ec83000 rw-p 00082000 08:01 27394082 /lib64/libm-2.5.so 396ee00000-396ee16000 r-xp 00000000 08:01 27394070 /lib64/libpthread-2.5.so 396ee16000-396f015000 ---p 00016000 08:01 27394070 /lib64/libpthread-2.5.so 396f015000-396f016000 r--p 00015000 08:01 27394070 /lib64/libpthread-2.5.so 396f016000-396f017000 rw-p 00016000 08:01 27394070 /lib64/libpthread-2.5.so 396f017000-396f01b000 rw-p 396f017000 00:00 0 3971200000-3971207000 r-xp 00000000 08:01 27394084 /lib64/librt-2.5.so 3971207000-3971407000 ---p 00007000 08:01 27394084 /lib64/librt-2.5.so 3971407000-3971408000 r--p 00007000 08:01 27394084 /lib64/librt-2.5.so 3971408000-3971409000 rw-p 00008000 08:01 27394084 /lib64/librt-2.5.so 2aed46b86000-2aed46b88000 rw-p 2aed46b86000 00:00 0 2aed46ba0000-2aed46c86000 r-xp 00000000 c96:9a5e 241766367 /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6.0.16 2aed46c86000-2aed46e86000 ---p 000e6000 c96:9a5e 241766367 /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6.0.16 2aed46e86000-2aed46e8e000 r--p 000e6000 c96:9a5e 241766367 /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6.0.16 2aed46e8e000-2aed46e90000 rw-p 000ee000 c96:9a5e 241766367 /software/compilers/gcc/4.6.1/lib64/libstdc++.so.6.0.16 2aed46e90000-2aed46ea6000 rw-p 2aed46e90000 00:00 0 2aed46ea6000-2aed46eb3000 r-xp 00000000 c96:9a5e 241766181 /software/compilers/gcc/4.6.1/lib64/libgomp.so.1.0.0 2aed46eb3000-2aed470b2000 ---p 0000d000 c96:9a5e 241766181 /software/compilers/gcc/4.6.1/lib64/libgomp.so.1.0.0 2aed470b2000-2aed470b3000 rw-p 0000c000 c96:9a5e 241766181 /software/compilers/gcc/4.6.1/lib64/libgomp.so.1.0.0 2aed470b3000-2aed470c8000 r-xp 00000000 c96:9a5e 241766007 /software/compilers/gcc/4.6.1/lib64/libgcc_s.so.1 2aed470c8000-2aed472c7000 ---p 00015000 c96:9a5e 241766007 Abandon (core dumped) Sébastien Boisvert U.
